Not directed at anyone, but never leave anything visible inside the car. Mail, purse, phone, keys, weapon or something that might look like a weapon, package with store logo, luggage, any little thinkg could tempt a perp to break in hoping it might be something useful. Parking garage, parking lot, street parking, your own driveway. Church parking lots are targets, as a perp would figure plenty of time while people are inside. We all know Christmas time is worse, especially if wrapped packages are visible, but any time is risky for leaving packages, merchandise, clothing, anything. Perps know that folks who park in a casino lot or garage may have valuables in their car. I don't know how many casinos have brought valet parking back, but valets aren't immune to temptation, and they know exactly what is in a car they park. Can't trust anybody.
