The headline is rather vague and seems to buy much of what's said in the actual article: that the cops raided this dude's home and charged him with obstruction when he got upset that they were raiding his home and stealing his shit.
Among the things they made off with as "evidence": computers, t-shirts, a fridge magnet, and a keffiyeh (that scarf traditionally made in Palestine). There's no mention in the article that this dude was anything other than a peaceful activist campaigning for a free Palestine.
Edit: I just read the arrest report and it's pretty standard cop overreach stuff. They raided his home, took his computers, thumb drives, etc. and the worst thing they found were "Plans indicating how to cause property damage during the protest;" and smoke bombs.
Definitely a true danger to the public. Best we lock him up so we can get back to bombing children.
