Wait – so these massive gang invasions of stores, smashing and grabbing by hordes of gang members who then wheel out shopping carts literally overflowing with expensive goods, is all because stores don’t have adequate staffing? 
It’s pretty hard for surveillance cameras to film a “strawman”.
Previous posts here are the straw men: full of attempts to minimize the extent of property crime in the SF-Bay area, to blame reports of high crime on conservative fear-mongering, and also a bunch of refutations to things that neither Maher nor anyone here has ever said, like “it’s illegal for employees to confront shoplifters”, “shoplifting is allowed in California”, or that thefts under $950 cannot be prosecuted in California (they just became misdemeanors rather than felonies).
But really, the point of posting the video is just that it’s pretty damn scary. These are dangerous organized gangs dealing in large-scale theft. The video shows several instances of them being arrested by what were essentially quasi-military SWAT teams. And this was in what I had thought was a fairly peaceful part of California, away from the big cities.
