Intentionally interfering with emergency services, for one.

Try blocking a major bridge in your home town for a day and see what crimes you're charged with.

In Canada as long as it’s in support of a sufficiently left-wing cause you won’t be charged with anything.

I think that it was fraud. Any non-politician who submitted false documents causing the Port Authority to close a bridge lane would be easily convicted of fraud, making knowingly false statements with the intent and effect of preventing the Port Authority from making full use of its valuable property. The Supreme Court ruling is pretty explicit that Bridget Kelly's status as a political aide is why she could not be convicted; because her boss had regulatory authority to close the lanes for honest reasons, the Port Authority has no property interest in any closure she orders, even if it was ordered for dishonest reasons.
