And how do I know this? Because even though everyone is making a big hullabaloo about those disrespectful yahoos being towed later in the morning, I personally drove by there around 5 a.m. this morning, and was stunned to see all those vehicles already there (possibly having been there all night, who knows?), as well as a white SUV police cruiser just across the street from there, with a clear line of sight to all of those vehicles and doing sweet fuck all about it.
Those trespassers were finally towed, but only after the outrage became sufficiently public. Until then, the cops were just fine with it.
As I have just explained, they were already there at 5 a.m., in full view of a police cruiser parked across the street, who seemed quite content to do nothing about it.
