On the state and local level I have a bias in favor of the police but I definitely do not give them the absolute benefit of the doubt anymore. At the Federal level I just save time and assume they are guilty.
This may be a bit harsh, but saying you support the police even though they have KNOWN issues and acknowledging they know they need to address them seems a bit squishy. Those “issues” have been around for decades. It’s a culture of thuggery and intimidation. Maybe even juiced up on Roids too.
Personally, the police,local, state and especially federal can ALL GO TO HELL!!
