Unprecedented Inauguration Security

What level of threat would warrant the level of security we are seeing, not only in Washington DC, but nationwide? Historically, when conservatives lose an election, we go back to work. Look at the eight years of Obama for example. We do not riot. The recent events on the 6th have been proven to be planned in advance, and were committed by leftists, BLM, and Antifa, so why all of the security? Could it be to deal with riots planned by the left? We believe so. You decide.
