commissioner, what extra steps are you taking? >> well, we're fortunate that over the past year mayor de blasio here in new york has funded us to the extent that we now have about a thousand more officers that will be focused on counterterrorism and crowd management. we have a new response group, 800 officers. we have a new critical response command, over 500 officers. they will be out at that parade. for a change we'll have great weather, low wind, the balloons will be up. we're expecting about three million people to be in new york city for that event. it's going to be a great event and it will be a safe and secure event. >> secretary johnson, we've had a heated debate about the syrian refugee issue, but there talking with law enforcement officials, you hear that if congress did anything, you'd like them focus on the visa waiver issue. explain. is it easier for an isis operative to get into this country to get a visa than it is for the refugee process?
