This is total alarmist misinformation. The "evidence of terrorism" was not "using Signal" or "carrying a first aid kit", it was taking part in an armed assault on an immigration facility where a dozen people set off fireworks and shot a police officer with an AR-15.

The prosecution used the presence of the first aid kit they carried during their armed assault, along with actual messages (not metadata) from a Signal chat to make the case that the attackers planned on using violence.

There are a lot of problems with this case, IMO the most dangerous part here is that adds legitimacy the (false) idea that "antifa" is an organization that exists. Something the Trump administration has been struggling to prove. This X post takes small details out of context.

1. Don't trust anything ever posted to X. Especially something that discourages the use of private messaging apps.

2. I highly recommend everyone report this this post to your admins and strongly recommend all instance admins ban/warn accounts like OP. If we want the fediverse to catch on it needs to be more factual, not knee jer.
