Is getting in trouble by the FBI more serious than getting in trouble by the police?

Federal crimes do involve FBI and even taking a girl across the state line for the purpose of having relations, is a federal crime and they will knock on your door. Also for computer crimes, using hate or terrorist threats over phone, by mail, computer or in federal buildings will get a private chat room of your own. Secret service will work with FBI if you like making your own money, defrauding a bank, using false IDs, stealing social security checks, poisoning your mailman and more. Check on your state laws that they refer to the FBI for a complete volume of crimes that can go Federal, like riots, FDIC insured companies (not only banks), even threatening to make a bomb can become a federal case. Good luck in your research and by the way, security guards come in many flavors, from a corporate door checker by a local agency, to a top clearance corporation where guards are sometimes federal agents. You never know who you are talking to even on the computer. If you want a secret to remain so, never tell anyone.
