I feel sorry for the Enforcers getting caught in what's coming. This guy didn't deserve to die, he was just a convenient symbol of the growing oppression in our Government that someone decided to take retribution against.
It's sad. It's regrettable. But I predict that there will be more of this to come. Government, doing what governments do to protect themselves, will use incidences like this to crack down on those of us still trying to follow their laws.
It was senseless to seek retribution on the guy driving the van. The person who sent him is the oppressor.
Though if it gets too dangerous to be the “face” of oppression, they might have trouble finding folks to fill these roles.
