The article says Cure was going at 100 MPH for 80 seconds after the officer put on his lights. Cure pulled over in the end, but that doesn't mean it's not a chase, which is why the cop ordered him out so quickly. 100 MPH is already more than just a speeding ticket, that's reckless endangerment. In general, 15 MPH above the speed limit is considered reckless. Add that to the chase, and that's why Cure was under arrest rather than just a ticket. I agree with you, the cop did nothing wrong here. He gave lawful orders, escalated force reasonably, attempted both his taser and his baton before firing as a last resort when he began to lose the fight and his own life became threatened, and administered first aid immediately.
I don't know why q47tx uses it, but there are a lot of niche support communities that would be very difficult to give up. Subs that encourage sobriety, give basic legal or medical advice to those that can't afford lawyers/doctors, and subs with resources for domestic violence are just a few examples. I don't begrudge anyone for continuing to use reddit if they use it for things like that. I find myself there often because unfortunately, it's basically the largest resource for user-curated information and solutions, and a lot of my google searches for particular issues are only solved by going to an answer there. The part where I'll judge someone is if they continue to mindlessly browse reddit, as I used to until the API fuckery, but for all those things, yeah, reddit is still the best, as much as I don't want it to be. Lemmy could get there eventually, but the simple fact is, it's not yet.
