It’s been done before… before the “Red Scare” there was the “Black Scare” - it’s where the trope of the “bomb-throwing anarchist” comes from.

It’s a valid tactic - but if it’s not carefully done and well thought through, it can end up creating a lot of blowback… as it did for the anarchist Alexander Berkman when he attempted to assassinate the capitalist Henry Clay Frick (hint - don’t assassinate a capitalist during a strike… if the striking workers thought that’d work they’d probably do it themselves).
