How is this any different than production giving people MAGA hats and Trump t-shirts and then placing them behind Trump at rallies, telling them to clap and smile for Trump only to remove/replace them if they aren't animated enough or in disagreement with whatever drivel Trump is spewing? This is called production. In the video you posted it stated that the police allowed protesters who were already there to move behind the reporters. It's not uncommon practice. Many times I have been out shooting protests myself and have seen news crews position people behind reporters.
Remember "Plaid shirt guy?" He and his friends were given MAGA hats and were told to clap and cheer for Trump, but when they failed to do so they were removed and replaced. So do Trump rallies always present the truth?

Or how about the time actors were hired (paid $50 bucks apiece) to attend/cheer/hold signs when Trump announced his run for office?
