Loud thumping noise that can heard three blocks away is a deliberate anti-social provocation. The culprits most often are black. Sometimes a car pulls along side mine at a light and is so loud that MY car rocks and vibrates. I certainly understand why it drove the shooter nuts. My house is constantly rattled by thugs driving down the boulevard behind my house; I resent the hell out of it. The law does nothing to stop it. A few more nationally publicized shootings might drive home a point to some of those cretins.
Right. It's a shame that people will be hurt and possibly die because our elected officials are too timid to address the problem and ban the subwoofers.
