I don’t know what it’s like in Mexico but in America the federal government is not supposed to spy on citizens.
I don’t believe they are DOJ - they are probably illegal aliens with stolen T-shirts.
In America, it's not spying to watch people engaged in public activities. If you have a parade, people can show up to watch, even the DOJ. If you stage a protest, people can show up to watch, even the DOJ.
I can't believe I actually have to explain this. The protests are staged to get attention. The protesters are ASKING FOR ATTENTION. LOL! Are you seriously contending that certain people can't watch, because they might work for someone you don't like? LOL. This is hillarious.
