If you want to get rid of qualified immunity how will you stop that side effect from happening?
My late father back in the day was a LEO and they had "false arrest insurance". Not sure today if LEOs have such.
What it would mean if they had to buy such is that we would have to budget more money to increase their pay. Not sure how many cities can increase their taxes to their citizens.
LEOs are different. They risk their lives daily to protect and serve. When LEOs in justified shootings get their fannies sued in civil court, something is wrong.
