Judge or DA gives someone probation, offers a plea bargain that avoids any jail time, or orders someone released from custody pending trial. Person then goes out and commits another crime. Should the Judge or DA be able to be sued by the victims?
This is one that happened around here a few years ago. Gunmen that shot and killed multiple students at Michigan State University was caught a year or so earlier carrying an illegal firearm as a felon. That would have been a felony with jail time, but the DA offered a plea bargain of carrying a loaded firearm inside a vehicle, even though he was on a bicycle at the time. Got probation.
Then police then later had complaints of him target shooting in his back yard in a residential neighborhood, yet did nothing as the DA had a policy of not charging gun crime violations without an underlying crime. Then that same individual went on a shooting spree on the MSU campus killing three and wounding 5 more. Without qualified immunity, the victims could sue the DA, Judge, or police personally for tens of millions for not sentencing him to jail before.
How about elected politicians being sued personally for actions during the covid lockdowns that caused a business to go bankrupt, or legislators being sued personally by someone for laws they passed.
