Yes, federal agents generally must follow state laws, but they have significant protections (immunity) under the Supremacy Clause for actions within their lawful federal duties, meaning states often can't prosecute them for lawful acts, though they can for serious crimes like murder, though federal removal processes can shift cases to federal court. The key is whether their actions were a reasonable part of carrying out federal duties; if they commit crimes, they can be held accountable, but state charges are complex and often lead to federal removal.

Can the federal government override state law?
