"H.R. 347 did make one noteworthy change, which may make it easier for the Secret Service to overuse or misuse the statute to arrest lawful protesters.
Without getting too much into the weeds, most crimes require the government to prove a certain state of mind. Under the original language of the law, you had to act "willfully and knowingly" when committing the crime. In short, you had to know your conduct was illegal. Under H.R. 347, you will simply need to act "knowingly," which here would mean that you know you're in a restricted area, but not necessarily that you're committing a crime.
Any time the government lowers the intent requirement, it makes it easier for a prosecutor to prove her case, and it gives law enforcement more discretion when enforcing the law. To be sure, this is of concern to the ACLU. We will monitor the implementation of H.R. 347 for any abuse or misuse."
