The person who did it probably thought it was a good idea. In the 60's and the 30's strikers would also get into fights with people crossing the picket line.

Picketers would puncture the car's tires of the people crossing the picket lines.

I actually heard a young couple, in their late twenties, talking about crossing the picket line just for fun. That's an actual quote: "we are going to buy something just to piss them off." Arrogant as they were, they were probably children of a rich family in Berverly Hill. Anyway I talked politely to them about the other shopping option one block away --Ralphs. They confronted the strikers, and they seemed to enjoy it.

When they came back from the store with their one tiny pack of Chewing gum, they started confronting the crowd of picketers again.

Later on the young woman would fight with a female striker (photo). Minutes after that the young man started to fight with a male striker (no photo).

Both initiated the fight. And strange enough they didn't seem on drug. Well you cannot be really sure.

The arrogance of those rich people has no ends.
