The department is working with the Secret Service and the Bureau of Alcohol, Tobacco, Firearms and Explosives to investigate the incident, the spokesperson added.

Seems pretty self-explanatory. What is there to investigate?

I will never understand this kind of “protest,” because it presumes that you have value to the people you are protesting. Israel certainly doesn’t give a fuck about a US citizens’ opinions, and the US government doesn’t know who you are. You are killing yourself to make a point to people who literally don’t care if you live or die, and any meaningful activism you could have done as an able-bodied person is lost forever.

People might remember that this happened, but it will be like a half-remembered dream when the next event oozes out of the ragebait news machine.

Based on what I leaned from the article about his final message, the protest wasn't for Israel's sake, it was to draw those living under the rule of a government's attention (whether Israel's, the U.S.'s, or wherever else's) to the situation. To point out that we are indeed living through a genocide perpetuated by our own government. Like I question his method, but realisticly speaking, you and I wouldn't be talking about it if he hadn't.

And maybe nothing will ultimately come of it, maybe it was a desperate act against his own powerlessness to stop it.

I would argue self immolation is a pretty powerful statement though, you weigh everything you are, everything you could be; against the hope that a message takes off somewhere.
