area, all taking these measures sort of keeping their eyes and ears open for anything suspicious. but it is important to note at this point, jim, there has been no credible threat tied to the actual ball drop event but certainly the nypd says no complacency. everybody will be on their toes ready to react to anything that should happen. >> all those measures you mentioned, i suppose many of them could be tied to concerns about a repeat of what we saw in berlin. how is the nypd preparing for all sorts of threats? i suppose the berlin threat is obviously top of mind right now. >> reporter: yeah. exactly right. that's why it's such an evolving plan with multilayers because once that did happen in berlin, the sort of truck attack, the same attack that they saw in nice, that's why they decided to build sort of again this fence with all these vehicles around the perimeter of times square. so it's a plan that anytime new threats come up it evolves.
