Smash and grabs are truly the perfect crime in SF. The odds of finding a laptop in the trunk are quite high due to the techies. I, like most residents, cannot hear a car alarm anymore - at this point they help me sleep. It is impossible to get caught - even if you were - the odds of the DA prosecuting you are low. In someways I agree: what is the point of processing a person with a misdemeanor and letting them out in 2 hours without followup.
Ironically, without smash and grabs things would be much worse. I would fear criminals would start hitting apartments. My apartment neighbor was violently assaulted and had her apartment ransacked (for a LAPTOP!). Every office I worked in SF was robbed at least once - no one was ever caught despite clear video. Thankfully, the DA does care about home invasions [I had detective interviews]. So my unpopular opinion is: if they are going to let the city decay into a crime ridden dystopia - leave smash and grabs alone. Let them break into cars. Insurance will cover the window - you can buy a new macbook pro. The next step of home invasions is much more terrifying. AND! With each smash and grab the victim will start voting correctly.
