... one might even start from the position of assuming every shooting is a false flag until proved otherwise?
So you believe the first part of your statement: "...almost every one a false flag" because... no one has "disproven" to your satisfaction an apriori premise/assumption/ hypothesis that all the shootings, bombings and BS truck/van assaults are false flags?
Making assumptions and then expecting others to treat them seriously never mind disprove them, isn't exactly rigorous thinking on the part of the proposer is it? In fact it's circular and self-reinforcing.
The onus of proof lies with the proposer: not with others. -Tristram Shandy's all round, barman!
