As far as being sued goes, I believe that Soverign Immunity protects them as long as they were acting in "line of duty".
Recall several years ago when a good number of those on this forum, not only bootlickers, got their panties in a wad because the police in different jurisdictions made mistakes? or omission on warrants and some individuals had to be released? Their reasoning was "As long as the Officer was acting in good faith", the warrant, mistakes?/omissions and all should stand.
Well, the SWAT team will maintain that they were acting in good faith.
