A few protesters stood on the streets holding signs urging people not to turn in guns.
One, Bruce Boyer, yelled at waiting drivers that they were supporting "the regime" by turning in guns.
Boyer, who calls himself the "chief instigator" of the local pro-gun group Sons of Liberty L.A., said the event is "a fraud" meant to convince the public that police are making the streets safer.
Instead of urging law-abiding citizens to turn guns in, Boyer said, police should encourage them to get more guns to protect themselves. ...
Referring to the other people in line, many of whom appeared elderly or middle-aged as they drove out, he added, "I would say that the people turning them in are the ones that should be keeping them. And I don't see many gangbangers in the line."
Johnson, the undercover officer, said some of the weapons were, in fact, gangbanger guns, and he was glad to get them off the streets.
