So when the Capitol police let in protesters, is that storming the Capitol? If you're suggesting that only the ones who forcibly entered the building should be arrested, then ok. However, plenty of them didn't actually enter the building and only entered spaces that the police allowed them to.
lol! are you kidding me? have you ever tried to visit the capital? no one can enter the capital without a prior security background clearance.
any 'cop' that 'let them in' was part of them in spirit.
I have been to the Capitol multiple times, actually. The last time I went was back in 2011, but yes, it is odd how the police let them get past the gates that were set up. If you don't believe me, go back and watch the footage. If you're suggesting that any cop that did that was complicit, then you'll have to blame the entire police presence. It wasn't just 1 or 2 guys doing it behind their backs.
It does present an interesting question though. Why would police do that? You seem to assume that it's because they supported the cause. I think a better explanation is that letting it escalate fits the desired narrative. Since the protesters were able to reach the building and enter it, they became easy scapegoats to drum up false patriotism among the left and the gullible.
