BALDWIN: Since the attacks here in Paris half a mile down the road from where I'm at, New York City police have seen a 200 percent increase in the number of what they are calling suspicious incident reports. The city has had to boost the number of detectives following up on all of these calls. We are looking at the NYPD. They are conducting anti-terror drills inside the subway system. This is happening as the U.S. is entering a busy holiday travel season. We have our justice correspondent, Evan Perez, standing by. I know, Evan, you are so close with a lot of people in law enforcement and a lot of tips coming into NYPD. How many of them do they have to see through as an investigation?</s>EVAN PEREZ, CNN JUSTICE CORRESPONDENT: They have to see every single one of them through. That's one of the difficult challenges of doing law enforcement in New York City. Everyone knows that the top target for terrorist groups, everybody from ISIS to al Qaeda. So that's what the NYPD does now is every single lead that comes in whether it comes from 911 or this toll number, all of it goes into this database. The FBI takes a look at it and sees whether there is something they need to look at and then the NYPD decides if they are going to track this down. Someone who ran out of gas and abandoned a car, something they have to check out. Or someone who posted threats on Snapchat or Facebook, they have to look at every single one of them. 500 of these investigations have been conducted so far this year -- Brooke?</s>BALDWIN: Evan Perez, we are so thankful for what they are doing as we are entering the holiday season.</s>PEREZ: Absolutely.</s>BALDWIN: Thank you so much. Coming up next, this.</s>BALDWIN: Black Lives Matter protests in Minneapolis hit by gunfire. Multiple demonstrators wounded. And now, two arrests, right after the break.
