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.

Exposing and Preventing FBI Spying
Responding to ACLU FOIA requests filed in 20 states on behalf of more than 150 organizations and individuals, the government has released documents that reveal FBI monitoring and infiltration by the FBI and local law enforcement, targeting political, environmental, anti-war and faith-based groups.
Our clients include advocates for the environment, animal rights, labor, religion, Native American rights, fair trade, grassroots politics, peace, social justice, nuclear disarmament, human rights and civil liberties. When the FBI invades the privacy of political and religious groups in the name of fighting terrorism, it abuses our trust and threatens our freedom. The public deserves to know who is being investigated and why.
