TRENTON, N.J. (CBS) -- New Jersey is preparing to make revisions to law enforcement's use of force policy. On Wednesday, Attorney General Gurbir Grewal held a virtual town hall to get the public's input.

"We need to look at a few things. One, we need to look at, as I said just a moment ago, the policies that we have in place now. We also need to collect data. Data can really tell us where we're at. We have to take a scientific approach," New Jersey Police Training Commission Commissioner Jiles Ship said.

"We definitely need to increase the training -- not just classroom training, situational training, scenario-based training, comprehensive looking at how we mesh all of our force options together, whether it's hands-on, using your firearm or enhanced mechanical device," Linden Police Chief Jonathan Parham said.
