Time and time again we see Police Chases end in injuries and death of innocent bystanders. Now some police dementspartments are taking steps to prevent the accidents. It is unacceptable collateral damage. Reporter a usa today investigation found that more than 5,000 bystanders and passengers have been killed in police car chases since 1979. Tens of thousand mr. Have been injured. And over 90 of all chases are for nonviolent crimes. Making the pursuit itself often more dangerous than the original violation. Its upsetting. Very upsetting. Reporter Jessica Rodriguez knows what it is look to lose a loved ones to a police pursuit. Her father ronaldo was killed after a long workday caught in the middle of a highspeed chase. There is no way he ever could have seen the suv coming his way until he was in the middle of the intersection. Reporter she shows us the dash cam video front tragic day. He is speeding up quick .

In the meantime, she has taken her cause to capitol hill. The goal is to hopefully get legislation to fund pursuit reduction technology. Reporter technology that she says can help reduce the number of needless deaths. How does it work . Can you walk me through it . Police in austin one of 20 departments across the country testing star chase, a gps tracking technology. When the officer feels a pursuit is likely to occur. He simply pushes one button a gps projectile compressed air fires from the front of the vehicle, attaches itself to the suspect vehicle. Reporter the tag contains a gps tracker the police can monitor remotely. Here in the command center they can track in real time the suspects whereabout and alert officers when it is safe to make an arrest. Officer carenas, patrols the streets of the east austin neighborhood he group in. Ready to go. Reporter looks like the tagging system made it safer not only for you, but the people out driving around . Motorists absolutely. We dont have to risk ourselves to try to catch the vehicle now. And it leaves our jurisdiction well, let neighboring sector know with vehicles entering. Reporter austin pd claims star chase has been a success. Since 2013 the system has been deployed nearly 40 times with 100 arrest rate with no crashes or injuries in the cases. They ordered ten more units at 5,000 apiece. How difficult is it to be the one pursuing . Its extremely difficult. You have to account for what the suspect is doing. Keep eyes on him. You have supervisors asking you whats going on . What are you doing . Where are you going . How fast are you going . What are the Road Conditions . Reporter while pursuing a suspect. Each Police Department has its own pursuit approximately see but all rely on the officers judgment on twhooitswhether to chase. Most do. Through intersections and and a half gating narrow residential streets. To find out firsthand what a police chase feels like we sought the help of travis yates, a veteran of the police deps.

Reporter in the pursuit drill my heart rate sky rockets. [ sirens blaring ] reporter up from 84 to over 170. Adrenaline surges through me. All i was doing in that moment was focusing on chasing. I was not really noticing too much else. I was trying my best to. But, again when you got the lights and the sirens going and adrenaline pumping it makes it pretty difficult to to really make a rational decisions. Reporter something that Police Officers we spoke with say they struggle to keep in mind when the surge to chase kicks in. It is real difficult. A lot of officers have a hard time dealing with it. Reporter most Police Officers are in it for the right reasons, theyre in it to serve, theyre in it to bring bad games to justice and justice to their victims. It is hard to let somebody go. With stricter regulations, jessica hopes other families will never have to experience a tragedy like she has. I know that there is a loss. Thats felt greatly. And when i look at this picture, thats what i see is that were one a big family and we were so happy. And now the pain that all of us live with since that day. It didnt have to happen.

Look at your kids eyes. Theyre so pretty. Reporter but are the reactions to these new glasses developed by a Company Called inchroma real or clever . Borrowing a pair from the company and embarking on our own nonscientific study of three color blind people. This is my room. Reporter meet maddux a fifth grader about to paint his bedroom. This i know is blue. They tell me. It looks purple. I think it has oranges in it. Reporter danielle an artist working with colors she cannot fully see. These dont have any labels on them. Having to figure out what color it is. Reporter and oscar. Who dreamed of being a Fighter Pilot until he discovered his condition prevented it. What color flowers do you see here . I see reddishpink ones over there. And these are yellow. These are bright yellow. Yeah. This is orangeyellow. Reporter all that could change by the end of the day when each of them will try on a pair of these glasses. We are selling these very quickly. Soon as we order 500 or 1,000 pairs are sold. Reporter Don Macpherson the chief scientist, he said initially he developed glasses as protective eyewear for surgeons. Made blocking wave lengths of light. Reporter then one day. I was playing in an ultimate frisbee game. My friend was color blind. He borrowed my glasses and said i can see the cones on the field. The lightbulb went off. Reporter this is how it works. Lenses contain a vertical filter that blocks out certain wave lengths helping the brain make distinctions between colors. For a Company Using a tag line color for the color blind. There is another distinction macpherson would look to make. Do you cure color blindness . Absolutely not. No. We help people perceive colors better with the eyewear. Certainly they cant give color to a color blind individual. Reporter dr. Mark frommer an eye surgeon from lennox hill hospital in new york doesnt believe the glasses can change the color blind eyes ability to see true colors. Reporter theyre not getting the rainbow. Theyre getting an aid. An optical device. Reporter macpherson disagrees. What are the promises you are making for people with color blindness . Improved quality of life. The world is wonderfully colored. To not fully experience that is a shame. Reporter will they receive any of the benefits . First we had all three tested for color blindness. So maddux this is a Screening Test we use in the office to test for partial or complete color deficiency. Try to do your best to see the number made up by the color dots. I dont see anything. Nothing. I dent seeont see any number. Tell me what you see . I dentont see anything there. This one . No. Might see a 6 there. Nothing there. Nothing. Reporter all three definitely color blind. The glasses cost up to 450. Come with a money back guarantee, and have competitors like o2m and color correction system.

Okay what happened . Turn around. Does it look any different . Kind of. Kind of. Not really. Oh well. Keep them on a little bit longer. Little disappointment huh . Yeah. Oh well. Across town danielle takes her turn. Wow. Its kind of intense to be able to see colors for the first time really. I dont know if it is the way theyre meant to be seen. Im pretty emotional about it. Reporter across the country oscar tries them on with his fiancee. This is amazing. Oh, my gosh. Reporter but his biggest reaction this traffic light. I can see that. Reporter until now oscar only knew the light was red because it was the one on top. Sorry. Im getting a little emotional about a streetlight. Two out of three of our candidates had strong visceral reactions. But inchroma predicted the outcome with their own online test. We wondered what would happen if danielle retook the color blindness test we gave her earlier wearing the glasses. We asked the guy what he thought would happen. Will people be able to recognize the numbers . Y. Yeah. Whereas they werent before . Yes. But it doesnt really prove anything. Reporter despite her amazed reaction to the glasses. Its kind of intense actually. Reporter danielles results on what many ophthalmologists call the Gold Standard color blindness test. Sorry. Unchanged. We did an unscientific study they took the test before the glasses and afterward. And they didnt show any change. How do you explain that . The test is not a valid test for measuring color deficiency. We have never used it. For the simple reason that the test is not designed to be used with a filter. Reporter macpherson claims there is a better test one he says they used in their clinical trials. We decided to have the test. The farnsworth exam with and without the glasses. To oscar the wouldbe pilot. Roll those 15 disks in the proper order in a gradual sequence increasing hue. Roipt results reporter the results without the glasses . 6 of 15. About half. Reporter with the glasses. We moved the expeerment to take full advantage of the sunglass style lenses. You had 8 you misidentified out of 15.

Reporter daniel and oscar say they couldnt care lisa but the test results. They say seeing is believing. Wow. Reporter and since that first day he tried them with us. Here and here.
