Your defense of Trump (that's what it is, you're saying this isn't abnormal for the US) is the same as Trump's defense of Putin's Russia where people are regularly thrown out of windows... including just yesterday:
The US president appeared to place the US and Russia on the same moral plane in an interview broadcast before the Super Bowl kicked off in Houston, Texas. Asked by the host, Bill O'Reilly, if he respected Putin, Trump replied: "I do respect Putin. Will I get along with him? I have no idea. It's very possible I won't."
O'Reilly said: "He's a killer, though. Putin's a killer."
"There are a lot of killers," Trump replied. "We've got a lot of killers. What, do you think our country's so innocent?"
