Yes planning a crime is a crime.More exactly, it is called "Conspiracy to commit X", where X is the crime being planned. There's a bit more difficulty in proving it, because the prosecution has to show that you knew that a crime was being planned and that you willingly (or knowingly) participated in that planning, but it's still a crime.Also, note that you can possibly be charged with a crime even if you are apprehended before you can actually commit the crime. For instance, if you and two buddies pull into a convenience store, take out your guns, and walk in, but are met with a bunch of police officers who arrest you before you actually stick up the place, you can be charged with Robbery, not just Conspiracy to Commit Robbery. The prosecution has to show that it is reasonable to assume you were about to commit a crime (i.e. you had your ski masks on when you walked in, guns drawn, not just walked into the store with guns in your belts), and that the crime was imminent (i.e about to happen, usually meaning in the next hour or so).
Either an accessory before or after the fact.
