Some douche bags spray painted my car last night. They also tagged the sidewalk right outside my house too. Not sure why, since I mainly keep to my self and don't really talk to anyone in my neighborhood. I doubt it's because of my Marine flag because there is a guy a block over who flies one too and his car and house were untouched. And I'm not sure how to find out who did it, or how to keep if from happening again. Any advice?
