Yes, and the worst part is, I think a lot of cops are not too many steps away from being this sadistic. Many of them seem to resort to a “jolt” just to get people to comply quickly, because that is easier for them than having a discussion.
They may not be shocking someone a dozen times, but once you have decided to use violence, not for self defense, but to achieve compliance, you have crossed a line that eventually leads to consequences like this case.
