counter terroristic teams and bomb-sniffing dogs and cameras are where a few people are expected to ring in the new year. we are "outfront" live from time square. meck ala, how is law enforcement stepping up security on what is one of the toughest nights of the year? >> reporter: it is one of the toughest nights of the year. but as you know the focus of time square is security and safety. this is one of those events that families and young people come people from all over the world come and so the presence from police is intense. we knew there would be 3500 police officers here normally but we were told they bolstered that force by about 200. they have hardened the perimeter and widened it. where you would normally have a certain block blocked off in the past years, you'll see that spread out more. as you mentioned, bomb-sniffing dogs and resources in the air.
