Anti-authoritarians, anti-hate activists, anti-racists, leftists, etc in USA,
please expect and be prepared for the (in my opinion) extremely probable brutal Trump-regime reaction to Charlie Kirk having been killed, no matter who did it or why.
If you have affinity groups, organizations, family and/or friend networks similarly minded and/or supportive, please ensure that you mutually have verified contact methods, access to sympathetic and/or good lawyers, etc.
It extremely probably (in my opinion) will not matter if you had absolutely nothing even remotely to do with the event per se.
