Racial oppression and poverty make everything more difficult, you're a highly paid developer so you don't have to experience it. It's quite possible that Philando Castile didn't have enough gas to get to the store to buy a new bulb, or the extra money for a spare one, or an internet connection to figure out how to do it in the first place, or access to a friend or family member with the resources to get it done. Hell, maybe he was on his way to the store to fix it when he was shot. Either way we don't need the confrontation, people with a broken taillight know that it's broken, don't confront them! It seems small, but maybe you don't quite comprehend paycheck to paycheck poverty. I'm talking real American poverty which is a stark reality for far too many minorities in this country, an issue of which is also contributing to the violence and the riots plaguing the US as of late.
