Can You Imagine What Would Happen to US Entertainers…

…if the UK demanded reciprocity? For this?

To wit:

Pop star Lily Allen has had her US work visa cancelled after arriving at Los Angeles International Airport.

She was held at the airport for five hours in connection with an arrest for an alleged assault in London in June.

The arrest arose from an incident outside a London nightclub in March and resulted in a caution for common assault.
