You’re wondering why ICE can’t arrest people for noise disturbances and the like? It’s because they don’t have any jurisdiction over the local laws.

In Oregon, federal law enforcement can arrest anyone that commits any crime in their presence, state or federal. They can also arrest anyone that they have probable cause to believe committed a serious crime (felony or Class A misdemeanor), state or federal.

It's pretty unlikely that noise disturbances are a criminal violation, rather than a civil one.
