Steel wires through the straps, and looks like a backpack. I'm also big enough that unless it is rip and run, or a clear and unambiguous threat to my life, I'm not as concerned, so having a strap which won't break is enough.

Most of the serious crime in Oakland is in places you won't accidentally go (although there's a sketch area a few blocks away from downtown, and on the other shore of Lake Merritt), by and against poor people, often one or more involved in gangs/drug entrepreneurship/whatever. Same as most cities.
I also don't like this implicit because it's "poor against poor" then somehow that's ok and we can ignore those statistics. Poor people are people too. Talk about gentrifying.....
Also, a lot of that current violence is due to war on drugs and after effects, so the best way to address it is to wind down the war on drugs.
I'm convinced 4-7pm Fridays is a great time to steal laptops from commuters; they're tired, it's relatively low traffic, OPD's response times are...not impressive, etc. It's really a 5-10 block area behind the stupid Auto Row and some sketchy semi-SRO housing in the area which is a problem. (Pro tip for cities: auto dealers are horrible for foot traffic.)
