The impound must be on one or two of the cars that were filmed, and then they determined that their registration had expired or had outstanding warrants and then the "selective impound" and tickets. Of course, if you were filmed doing a 50 MPH burnout in the parking lot, you might expect to get a ticket and/or impound.

I really doubt they could impound "all" of the cars. There is no law against "gathering" since the Revolutionary War.

The police are just trying to cut down on the street racing. Take a look at the UK. They have cameras everywhere to cut down on crime.

Sounds like a tactic the IRS uses. Find a celebrity and do an audit in the springtime, and make sure the story hits all of the newspapers. Puts some fear in some people and they decide to start paying taxes.
