When I went college touring, I saw at least 1 or 2 implimented a safety mechanism wherein there is a huge button you cam press on a pole if someone attacks.
My suggestion is to start planting cameras all around your town. It's worked before I've seen in traffic. You could make out the dead body in the back of the truck, one of the freakiest revelations I've been presented with, on Forensic Files when I used to watch until I started noticing too many reruns. I think most of it is old stuff.
I don't see why we can't always use DNA or footprint residue to see if the crime is someone they know.
By having all these prevention mechanisms, we can discourage criminals from carrying out the deed.
I think an even bigger problem is those in society with big mouths, saying everyone is bad and in trouble for little things when they felt upset. However, these people are innocent yet get stormed at by certain kinds of people in society. There are goody 2 shoes who just wanna bother people and make them look bad by saying they back talked them in thought, when they were the ones who started being mean. I have people do that to me all the time. It happened that way online, and I got kicked out most of the time when I wasn't even saying anything bad back but just arguing lightly moreso. This was 2008. I've lost a lot along the way, including my dignity. I don't know who starts these thoughts, but they all seem to think together.
Good show!
