least. >> reporter: but as cab drivers and company operators sat in the room, it became clear the commission records didn't back up the statistics, with maybe a few dozen complaints, not 1400. >> 1,400 people per year, which is a big number. but i don't think that that matches up with what you've told us today, so i'm trying to figure this out. >> reporter: taxi commission chairman ron linton said his agency was hampered pie a lack of computerized statistics and different standards for reporting crimes. >> what you have today are a statistical report based off the top of my head

good accounting of what's going on out there. >> reporter: and the general manager of yellow cabs said the inaccurate data tarnishes all drivers. >> in eight years, i've had no complaints of sexual harassment or anything to that effect. i think you've heard a lot of numbers being thrown around, careless comments being now and now the council is asking for the facts. >> reporter: the council told

you know, that's kid of the unfortunate thing. you could get used to it but you can't. now we've got rain moving in. as a matter of fact, it's time to find those umbrellas again. we have that rain that will most likely move in tomorrow but really the day on friday is when we're looking at most of the rain making its way through and it will be a little bit on the tropical side. right now anything but. low humidity, plenty of sunshine, just a gorgeous, gorgeous day across our region. current temperature right now sitting at 80 degrees. dew point at 54. that is nice and comfortable. that humidity only at 40%. winds out of the south at 8 miles per hour. another fantastic day will lead to a very, very nice evening. as you're making your way out and about tonight, 77 in frederick. 80 la plata, 82 in fredericksburg and temperatures around 79 in culpeper. temperatures right where they should be this time of year, right around that average. average right now about 80 to 81 degrees. storm team 4 radar showing things are all clear in our region but that is not the case down to the south. we've got a possible tropical system down here. it could become our first tropical depression of the season, maybe our first named storm. got to have a tough time becoming named. but it's going to bring all this moisture. take a look at all that rain, all that moisture straight up the coast and move it into our area. we're going to have two areas of rain, one friday morning and another friday afternoon. first off let's start off with tomorrow. notice 8:00 tomorrow morning, plenty of cloud cover. then during the afternoon around 1:00, notice the rain from the i-95 corridor back to the west. if you live back along the blue ridge and back towards winchester, i-81, you have the best chance of seeing that rain tomorrow. east of i-95 a lot less of a chance. so tomorrow not a washout for most of us. by 6:00, still some scattered showers around an even some of those down around towards portions of southern maryland and back towards the west. i think most of the rain will be back to the west but you can't rule it out anyway. friday morning, 9:30, rain. across the entire area, including heavy rain down to the south and throughout the entire afternoon the potential is there for some very heavy rain. we could get 1 to 2 inches of rain from this so this is something we'll be watching out for closely. by 11:00 friday night it's moving out of here and that's good news for your weekend, at least for our saturday. 62 degrees in washington tonight. 57 in gaithersburg, 58 manassas. most of the shower activity west of i-95 but we could see them around the interior. high temperatures around 80 degrees inside the district. 82 on friday with that rain, 84 on saturday and then a high of 85 on sunday. another chance of showers and maybe a few thunderstorms coming up on sunday but not a washout either day. monday, temperature back to 87 degrees. that looks like the warm day with a good chance of storms on monday afternoon. so right now the biggest threat is sometime tomorrow to the west and all day on friday. the country's drone program has taken center stage in recent weeks after president obama outlined changes to limit the cases in which strikes could be used. nbc news chief foreign correspondent richard engel joins us now to talk about his investigation into this program. richard, what did you find? >> reporter: we obtained some documents that describe about a year's worth of drone strikes in pakistan, and this investigation reveals that in some cases the united states is not entirely certain who it is killing and not entirely certain how many people are being killed. yet in both of these cases, the united states claims that there are no civilian casualties, an almost perfect record. so we look into these documents, we look at what they describe and raise some questions about not necessarily the use of the drones themselves and how precise the weapon is, but how precise is the selection of targets and how do we really know who we're killing and how do we really know there are no civilians involved. the conclusions we came up with is we don't. there's quite a bit of ambiguity in this program that is described almost universally by administration officials as almost flawless, because they don't acknowledge almost any room for error. >> and the american public of course overwhelmingly supports this drone program according to the latest nbc poll. do you think the american public is fully aware of the issues? because it's controversial. you hear pros, you hear cons. do you think it's really on their radar, so to speak? >> i do not think so at all. usually the american public hears about drone strikes and this is the most one-sided war in history, according to an expert we spoke to today. several thousand people have been killed by drone strikes in noncombat zones and there's been no american troops involved direct directly, no one at risk. so if you ask the average american, it seems like a very easy bargain. we're killing america's enemies with no risk to american soldiers. but the question that this investigation is raising is how do we know we're only killing american enemies? who gets to make that determination and how do we know that certain that no civilians are being killed? and the documents that we've seen suggest that in about a quarter of the cases, we're not sure the specific identities of the militants who are involved or if they really are militants. >> richard engel, thank you so much. we look forward to your report tonight. you can watch richard's full report on "nightly news with brian williams" that starts at 7:00 right here on nbc4. a face-off

through that at-bat. >> i got up there, no outs, bases loaded and, you know, he throws pretty firm. so i wasn't trying to do much with him but get something up. obviously i kept fouling a bunch of those off. i got one i could handle and was able to get it far enough out and he was able to score. and then the dog pile after. >> surviving that thing seems a challenge in itself. >> yeah, it really -- i was joking with suzuki, i said my neck is a little sore from you jumping on me last night. no, it was fun. it was a big win for our team. >> reporter: a lot of guys hoping it's a turn-around for this team. >> i think it was a big win to come back like that. we haven't done that all year, to score some runs in the last inning there. so i think it's a step in the right direction for sure. >>

have fun with it out there, just react to the ball off the bat. >> reporter: i know the guys are giving you a hard time because you have such a big fan club being from howard county and you have a job
