When protestors were done throwing bricks and water bottles at police, they tried to scale the White House fence. Liberals were pissed at the notion that reinforcements went up and they mocked Trump for staying in a safe location? Why are Liberals pissed at protestor storming the Capitol? Are you going to be upset about reinforced security going up? Are you mocking Pelosi and Schumer for being led to safety the same way Trump was? Or, is anyone going to be objective about security in DC when it comes to Protestors and the violence and destruction that occurs?
Well, looking back at the recent past, those who scale the WH fence (if you can manage it) don't do it in hundreds.

It's usually just a few people or one person. Easy to see coming, should be easy to take care of, especially if you have the type of weapons the Secret Service and other security personnel have. The President also has a security bunker with top of the line protection that he can retreat to. Those protesters never had any chance of getting within 100 yards of Trump.
What happened on Wednesday was an insurrection. It was an attempt to overthrow the US government. Interrupting a Constitutional procedure with the intent of overturning a free and fair election. Two pipe bombs found on the ground, multiple people arrested with and seen carrying weapons, a few people carrying around zip ties (gee, wonder what those were for?). Capitol steps rushed, windows broken, some Capitol police chased around by the mob while others took selfies. This was no protest. I shudder to think what would have happened had these yahoos gotten a hold of Congressmen or Senators. This mob was literally within feet of these people who were unarmed and defenseless.
