There are significant crimes that can be charged by the state or federal authorities that enhance or add long term jail sentences to a charge. The allegations of an attempt to commit a crime carry the same weight as actually committing the crime. If you are part of a crime alleged, you can be charged as an accessory or a conspirator. Conspiracy to commit a crime also carries as much penalty as the crime itself. And you may not even know you are part of the conspiracy!
Some crimes carry longer term penalties even though they are seen as victimless, like gambling and perjury. Perjury is intentionally making a false statement under oath, and filing a false statement is intentionally making a false statement to police in their investigations. For that you can also be charged with interfering with an officer.
