Just a matter of time before Antifa becomes armed. I would expect to see foreign supplied mercenaries and weapons courtesy of Soros and terrorist groups. I could see this as the next civil war. However, well armed US citizens will defend their homes and communities and the US military may be needed to crush this rebellion. If violence becomes wide spread look for the traitor Obama to beg for UN “peace keepers”. The prospect of foreign troops on US soil will be the end of the leftist uprising and bring about many executions for treason.
They are already armed. All they need is to get together. Right now its fractured organizations with small groups within each city.
If I were the police, I would be very concerned and watchful.
Antifa is already armed.
The have posted videos of their volunteers training with firearms. The students look pretty foolish, but the trainers know what they are doing. And some of those students will eventually know what they are doing too.
What Antifa has not done yet is use arms for targeted assassinations of opponents. They have not used firearms (yet) at an opposition political rally.
That is probably coming.
