The 'Rats have a problem.
Anything in the way of mass casualty events whose narrative favours the Democrat's election prospects will be seen as too much of a co-incidence to be genuine.
The Democrats will get blame, not electoral benefit.
False Flag events are now firmly established in the national consciousness in the same way as fake news.
Nothing can save them; they can only make things worse for themselves because there are too many informers in their ranks for them to get away with anything.
Some people just don't want to hang, and turning informer has far more chance of success than another hare-brained false flag event.
