I'm entitled to my own opinion.
Do I think LE would shoot private citizens if directed? 50/50, some would quit when it got to the point of taking guns, the ones that will take guns will definitely shoot you.
When I started out as a cop in the 90's it was very difficult to find a liberal progressive who would out themselves witin your ranks, as time went by it was obvious that these types became more obundant and kind of took over, the reason is departments found that they got more money if they went along with things, police have also become more militarized both in amorment and policy, and have been trained to have an (us against them mentality).
20 years ago cops would never take guns or follow orders to shoot you. Today is different, people are different. The cops today have been conditioned to do this, They know it's coming and I am sure most are a ball of stress because of it. The truth is many of them will go along with whatever they are told for self preservation, they have families, mortgages and don't have the freedom not to take orders.
The military is a different story, I would say 90% of them would refuse orders to harm americans. The military has a different mentality than cops, they are trained to love this county and the people within it, cops are trained to hate the country and the people within it.
