We allow the police to infringe on people's human rights for the good of society. That's not just the standard here, it's the standard around the world. Every country in the world allows police to stop people while they're travelling - infringing that human right - and question what they're up to. Every country in the world allows police to handcuff and imprison people.
If Pat had have been living in the most socialist, left-wing country in Scandinavia and the police got a tip-off there was an active shooter in his house he would have been treated the same way; although he'd likely be Baker Acted after his outburst in countries with decent mental healthcare.
The use of force by the state is always going to look ugly, but that doesn't mean it's always wrong.
(You might find
Donut Operator's channel useful. He's an ex-SWAT officer who breaks down police incidents, explaining why they act the way they act. You don't have to agree with his politics - I sure as shit don't - but he'll change your mind on police stuff. Wonder why police don't just tase/capstun people? He's got video of a guy holed up in a hotel room with a knife, who shrugs off a couple of tasers, some capstun, and then I think bean-bag round number eight finally slows him enough the police can swarm him. Wonder why cops are so quick to shoot armed bad guys? He's got video of a copy who doesn't, and just follows a suspect down the street until the suspect takes an old guy hostage. How about those
Armoured Personnel Carriers that were so controversial after the Ferguson shooting? Etc.)
