You gripe, I gripe. If people in my neighborhood would lock their car doors and stop leaving valuable stuff in their cars than car prowls would go down. When I used to be on NextDoor, there would be at least one post a week where someones car got broken into and their wallet, purse or laptop was stolen. I've been to neighborhood crime prevention meetings where people yell at the Captain that they want all the car break ins stopped. The captain says, lock your car and stop leaving valuable stuff in there, we try to catch them but we can't catch them all and you folks being more defensive will make a bigger difference than we can. The people say, Captain, stop the care break ins again... I know some of the cops on the night shift. They would love to make some arrests but the reality is even if they do the guys won't be off the street very long. If people would just lock their fucking doors and stop leaving their valuables in plain site thieves would move on to easier neighborhoods. CAAT sounds like bullshit btw.
Locking your doors just means you get your window broken as an added bonus. Imo leaving the car locked or unlocked doesn't really change much but removing valuables does. If the local crackhead looks through your car finds nothing and moves on there isnt any damage except the uncomfortable feeling that someone when through your shit looking for valuables.
Breaking windows make a lot of noise in a dense urban neighborhood. I don't know anyone who's had their windows broken. I do know one guy who had their rag top cut open. Leaving your door unlocked means that you have a dead battery in the morning. For some reason, I'm guessing that it's in to make less noise, everyone's door is left open after they get car shopped.
