Car Jacking: Do you lock your car doors immediately upon entering your car?

[scarlett]

I started locking my car when I lived in Shreveport due to all the car jackings downtown and this is where I worked. Now it's just a habit and I never leave my purse on the seat because they will break your window to get it and by the time the shock of it happening goes away they have your purse. I leave my purse at my feet or in the backseat and I have a coupe so there is no back window close to see the purse.
