Sen. Charles Schumer wants a federal law to prohibit trespassing on big bridges or structures like the Statue of Liberty after incidents involving people who scaled the Brooklyn Bridge and World Trade Center.

The New York Democrat says Monday that his proposal would make trespassing on critical infrastructure like major bridges or important buildings punishable by up to five years in prison.

A Russian tourist was arrested last summer after climbing the Brooklyn Bridge. Earlier in the summer, two artists claimed responsibility after American flags atop the bridge were replaced with white ones. In another incident this spring, a teen climbed the World Trade Center’s tower.

Schumer says such actions can be dangerous to the perpetrators and for commuters and emergency crews who respond to the incidents.
