Yes, to protect their officers, and I think they see the value in protecting the community at large as well.
The example an officer gave me once was that they get an order from the court that says Joe Blow, who just beat up his wife, can't have any guns. When they go to his house, if they don't know how many guns Joe Blow has and which guns they are, how do they know they got them all?
So I think that's an example of how law enforcement would see that as a community protection program.
