"Guess we are moving past breaking windows!" said tipster Paul, who sent in this photo of a van with all four tires removed.

"We are all used to auto break-ins, but some miscreant has taken it to a new level," reported a second tipster:

"On Castro Street, between 21st and 22nd, a car was put on blocks and stripped of its tires over the weekend. The car is still parked on the west side of Castro ... Amazing that someone was able to get away with this, as it must have taken some time to accomplish."
