Surely that's a libellous thing to say, or is there no rule of law in the USA these days?

Luigi has been accused of the shooting, but there's discrepancies with the possibly illegal search of his backpack and the body cameras of the police were turned off for 11 minutes which raises suspicions of planted evidence.

You appear to be based in the UK. Speech laws are very different in the US. It is a mistake to project your understanding of censorious UK speech laws on us.

Unlike the UK, expressing opinion is inherently legal here. What would be illegal is lying about specific facts, or expressing opinion based on secret facts you falsely claim to have. However, the standard for damaging a public figure, which Mangione certainly is, is very high -- Mangione would need to show "actual malice" (that is, that the speaker knew or should have known they were making false statements).
