There are always two sides to the story.
Before jumping to conclusions you should hear the other side, call up the town police department and ask them about the situation if you really care.
Otherwise it’s just one angry guys theory and message without a rebuttal. This isn’t what this country is based on. Things get taken to court, both sides present their stories and the judge makes a ruling.
So far to me all it looks like is a guy was putting up political signs without a proper permit, illegally due to zoning in a residential neighborhood, which were removed by the cops. They may or may not have given him a notice prior, but then again it also appears that they didn’t fine him $100 for each offense either.
