Four arrested as 200,000 attend pro-Palestine march in London

Note the focus on the 0.0025% arrests NOT the 200,0 who marched.

Then in the detail:

A man was arrested on suspicion of a terrorism-related offence in relation to inviting support for a proscribed organisation, the Metropolitan Police said. The man has been taken to a police station in central London and remains in custody.

Three further arrests were made, one person on suspicion of a racially aggravated public order offence and two others on suspicion of causing harassment, alarm and distress.

So the first one sounds like someone wearing a Hezbollah shirt and the others sound like they could have been counter protestors? In any event it's a miniscule number.

They close with the greased lie:

The war began with Hamas’s 7 October attack that resulted in about 1,160 deaths in Israel, mostly civilians.

Israel’s retaliatory campaign has killed at least 32,705 people, mostly women and children, according to Gaza’s health ministry

Amazingly they dropped the "Hamas-run health ministry".
