By and large guns don't provide security.
There are a lot more creative ways to protest violently though!
The election system distorts the vote quite dramatically in the US, that's true.
However, depending on where you're from left has quite a different meaning from what Americans mean when they say left. E.g. the Democrats don't want to dismantle capitalism or expropriate real estate companies (the city of Berlin seriously looked into this option). Center left has a similar shift in meaning in other countries.
I have compact view. I tap on a thumbnail to make the image "full screen". In short succession I tap on the screen once, then touch and drag, which zooms the image.
Since I have it set to dismiss/leave "full screen" via of images by swiping the image up or down I need the tap before dragging to zoom into the image.
I don't understand the "that's no how PDFs work" criticism.
Removing data from the original file is the whole point of the exercise! Of course unique tokens can be hidden in plain sight in images, letter spacing, etc. If we want to make sure to remove that we need to degrade the quality of the PDF so that this information is lost in said lossy conversion.
I think we kinda misunderstand what the other person is saying/what they imagine the outcome to be. There's a crass culture difference here.
In the UK (and presumably most other European countries) the police would 100% escalate things if they see someone with a gun near a large aggregation of people. Carrying guns like that is simply illegal and the only reasonable deduction is that you carry a gun because you want to use it - i.e. you are about to commit murder.
Police violence against protesters is usually limited to water cannons and tear gas, maybe rubber bullets. Protester violence is rare, sometimes throwing rocks, maybe Molotov cocktails and burning cars.
