The most commonly cited is 42USC1983, titled Civil action for deprivation of rights

Every person who, under color of any statute, ordinance, regulation, custom, or usage, of any State or Territory or the District of Columbia, subjects, or causes to be subjected, any citizen of the United States or other person within the jurisdiction thereof to the deprivation of any rights, privileges, or immunities secured by the Constitution and laws, shall be liable to the party injured in an action at law, suit in equity, or other proper proceeding for redress...

42USC1985 Conspiracy to interfere with civil rights which is applicable to anyone but is still only a civil action.

(3) Depriving persons of rights or privileges
If two or more persons in any State ... conspire ... for the purpose of depriving, either directly or indirectly, any person ... of equal privileges and immunities under the laws
...
in any case of conspiracy set forth in this section, if one or more persons engaged therein do, or cause to be done, any act in furtherance of the object of such conspiracy, whereby another is ... deprived of having and exercising any right or privilege of a citizen of the United States, the party so injured or deprived may have an action for the recovery of damages occasioned by such injury or deprivation, against any one or more of the conspirators.

18USC241 Conspiracy against rights, however, is a felony & is applicable to anyone.

If two or more persons conspire to injure, oppress, threaten, or intimidate any person in any State ... in the free exercise or enjoyment of any right or privilege secured to him by the Constitution or laws of the United States, or because of his having so exercised the same
...
They shall be fined under this title or imprisoned not more than ten years, or both;
and ... if such acts include kidnapping or an attempt to kidnap... they shall be fined under this title or imprisoned for any term of years or for life, or both, or may be sentenced to death.

I really wish we could get that one used / prosecuted more often against officers who misbehave.
