Police immigration notices

Explain it like I'm 5

Police would try to find the immigration status of people charged with certain serious crimes. If they cannot find out, they would tell federal immigration officials.

Yes vote

Law enforcement must notify the U.S. Department of Homeland Security within 72 hours in specified cases when immigration status cannot be determined.

No vote

Current Colorado rules on sharing immigration information remain in place.

The question to ask yourself

Should local police alert federal immigration officials before a person has been convicted?

The case for

  • May help federal officials identify people accused of violent crimes or people with prior felony convictions.
  • Creates one statewide reporting rule for these cases.
  • Requires notice, not a new local power to arrest or deport people.

The case against

Money
The official estimate is about $60,000 for state system updates, with no direct tax increase.
Don't be misled
It is misleading to say this applies only to people convicted of violent crimes, because it also covers certain charges and prior felony convictions.
