Wow Susan.......I work with cops all the time, when they stop by my house they are forever telling me to lock up...you need better security etc. I guess when you work and see the dark side of humanity, you don't trust anyone.
For the question...I always lock up at night, but not during the day. Probably not bright. I never lock my car unless I have something in it. My husband locks his all the time, and his car is the one they broke into.
