False flag operations have occurred: yes.
So have false claims of false flag operations, especially from those whose knee jerk reaction is “but my side would NEVER”.
So it’s not very useful as a means of distinguishing in any specific case.
But very useful for those who want to go on claiming “but my side would NEVER.”
Looking at the probabilities: nothing’s impossible, but one side
- has previously committed multiple acts of violence (mostly on property, some on people),
- made far more threats of violence,
- has a tendency to dwell on violent imagery,
- justifies its violence by whipping up hysteria & hyperbole about non-existent “genocides”
- seems to be losing.
But obviously: we don’t know.
I hope the workmen are recovering & the person was caught.
Edited to add: I first heard the “razor blades under posters” story in the 70s, when my mates & I used to scrape National Front posters off walls.
It was a lot of posters, but nobody I knew ever found any sharps (in fact I used to wonder if it wasn’t a story made up to encourage you to leave them up…)
More recently a TRA councillor round my way got into the papers, claiming he’d found razors under “hateful stickers”.
I know he was lying because a) he published his photos of the stickers with not a shred of a blade to be seen b) they were on curved surfaces & I have no idea how you’d manage it, & c) I’d put them there myself.
