I wasn't trying to relate it to the other deaths, just that IMO, in this particular case, being foreign was probably the reason. Also, its' been widely reported he was filming the protesters with his phone, not participating in them.
I base it off of personal experience. This is not to say most people there are like that, but rather, that there are a few that will lash out violently against "foreigners" in these types of situations. Much like being white and being stuck in the middle of the Watts and LA riots.
