Authorities attribute the drop to a number of things, including technology.

“A lot of people believe it’s the sociology of our environment. A lot of kids and youthful individuals are spending a lot more time on the Internet, which means they’re indoors a lot more. They’re not on the streets involved in street-level activities,” Lt. Neiman said.
