This seems like an old technique.
In the UK in the 1930s, the British Union of Fascists was trying to gain political power. British communists would show up at rallies and start fights with the British Fascists. The police then made it a practice of shutting down rallies by the British Fascists because “they were violent”.
I’m not in any way defending fascists (British or otherwise) but those “violent rallies” from the 1930s were basically fascists defending themselves when they were attacked by communists. The fascists got punished by the government and the communists won the day.
Now today, the Jews are punished by the government for defending themselves against terrorists.
The government was letting the pro-Palestinians continue their protests, but since the counterprotests, they finally went in to stop them.
What's happening seems more like what happened with the BLM and Antifa riots. The government let them continue, then conservatives showed up to counterprotest, were beat up, and then the government came in and arrested the conservatives.
It's not about who started the protest or who the counterprotesters were. It's more about which side is favored by the government.
