Just reading this makes me sick.
I have been dealing with a lot of scumbags lately, and it has really affected my perception of the world.
I need a sign that there is still good left in the world, news like this is far too common.
Asshole thugs like this need to be taught a lesson, and made an example of.
Your dad sounds like a tough individual though, its admirable that he doesn't back down, but I would hate to hear of this happening again.
It would be great if he could carry some kind of self defense weapon....the spray or whatever is legal.
My grandfather was a cop in San Fransisco, he responded to a lot of calls from Taxi drivers.....it sounds like quite a dangerous job.
