US Constitution and the 1st Amendment does not apply in Federal Buildings?

In this video I was producing footage for my upcoming documentary titled #Stolen. Part of the documentary alleges crimes being actively conducted in the local federal BLM office. In the video you clearly see hostility toward the first amendment by our federal government. Don't worry, I was able to get undercover video for the documentary. That will be coming soon. #WhoIsBryguy1955 #HelloAnna #TheNeverEndingLetter #Shield5 #TheEasyWay
