Nope. Won't wash. No paramedics means no injuries. Period. Cops were walking around the body freely for three hours, it wasn't a dangerous mob situation at the time requiring police evacuation of the shooter. If he was hurt, a paramedic would have been called and would have been seen on-site.
This whole thing stinks. The pep was a thug who attacked a cop. But the cops are walking around pointing loaded rifles at people and cursing them. Either this is the crudest psyop ever made to create riots, or the stupidest police force in the country.
Dunno about Missouri, but around here it is dead common for paramedics to see and treat someone at the scene, then have a family or member or friend take them to the hospital for further treatment. If there’s no urgency, and no other reason they really need to take someone themselves, they have other things to do.
Plus ambulances are pricey, and insurance won’t necessarily cover it.
