Yes, all member agencies of the Intelligence Community have common databases where their employees can all access the same information - often on a need-to-know basis and with proper clearance - in order to assemble the best possible intelligence reports. If the CIA, FBI, NSA, DIA, etc didn't share the information they know with each other then each would be missing pieces of the puzzle, so to speak, and this would lead to a very unorganized intelligence system and bad, incomplete intelligence reports.
FBI, CIA, NSA.
The NSA and FBI can pull the "Federal" jurisdiction card in some cases and take control of an alleged criminal. Technically the CIA has no jurisdiction inside the US.

Like anyone else, they politely ask for information.
The security agencies, like the NSA, CIA, Homeland Security and the FBI.
The NSA, or National Security Agency, has an annual budget but it is classified due to the nature of the work it does. It would be along the lines of what the CIA or FBI gets annually.
he would get caught and go to jail
There are a couple of parts of the government that has secret agents. The CIA, FBI, and NSA could all have secret agents working with them.
Well it depends on what you are intereseted in. The CIA is more convert information and more secretive work. This is wear spies come into play. The FBI is more like a higher police who go into more dangerous situations, they motly catch small bad guys unlike the CIA who capture terrosits and people like that. Personally I prefer the CIA.
Politics are a very important piece of what the FBI does, somewhat like the CIA. For example if you have a leader who is publicly in favor or puts legislation for the legalization of weed, or cannabis he can order that the FBI decimalize drug offenses, or he can take certain staff members out of the organization that do not agree with the policy's views. All of this falls under the checks and balances theory, all the other political branches check on each other. For example if your an American you know what's happening with the NSA etc... those organizations like the FBI,CIA, and the NSA rely on the other branches. if a law is found unconstitutional by the Supreme Court under the judicial branch they can demand the law be removed, or congress under the Legislative branch can demand that the FBI don't execute operations against the laws.
