if a case is brought at the state level, it can be removed to Federal court - delay tactics, etc.

Doesn't matter. State law will control, not federal law. You need to learn about the law.

I know state law controls Jerry, but it does matter. Note "delay tactics, etc." It's a tactical decision.

"Removing a state case against an ICE officer to federal court—often based on the federal officer removal statute for acts done "under color of office"—can inhibit or slow the case by changing the venue to a more favorable federal forum, potentially widening the jury pool, and utilizing different procedural rules. It often causes procedural delays, as a federal judge must first decide if the case should remain in federal court or be remanded.

Procedural Delays and Venue Shift: The removal process itself causes delays, as the case is temporarily paused while federal judges determine if the officer was acting within their federal authority, notes The Guardian.
Federal Immunity Protections: Federal courts may be more inclined to uphold federal immunity defenses, which can protect officers from state-level liability for actions taken while performing their duties, notes The Guardian.
Different Legal Standards: Federal court may offer more favorable procedural rules, a larger, potentially more sympathetic jury pool, and federal judges who may be more inclined toward the officer's defense, notes Isaac Wiles.

These factors can significantly slow down the litigation process and potentially lead to the dismissal of charges if the officer is found to be immune, as indicated in the context of federal officer removal statutes."
