My Mom has had her Accord broken into twice in the last week. She lives in S. FW. All she has is a car port. Both times a window has been smashed out. The first time they stole a gas card she shouldn't have left in the car. (Mom! What were you thinking?) This morning all they did was smash another window. Doors were still locked.
She doesn't have a car alarm. Not sure how much it would help anyway. Moving is not an option. FW Police say they will step up patrols. meh...
I could suggest leaving the doors unlocked but that might create new issues. My mom will not arm herself. :(
