Arguably, because a person of interest may cross the border into the country and then travel around domestically.

There has been no credible argument why this logic is acceptable for CBP and ICE but not FBI or DEA.

Why are the misdemeanor civil violators ICE chases so important that federal laws no longer apply, when until a year ago it was generally understood that agencies like DEA had guardrails even when trying to apprehend people on felony charges?

If this stands, there is no logically consistent rationale for DEA not being able to perform warrantless wiretaps of all communications, etc.

There’s a new sheriff in town in case you hadn’t noticed.
