Be careful if you are a Canadian in the US!

You're pulling one sentence out of my post.

My point is that it is likely that an "invalid license" is used to arrest non-citizens in an attempt to identify illegal aliens and have them deported.

This type of policy is focused on Hispanics and is pretty much ignored (or lauded) by the public and media. Seems a nice Canadian white woman got the treatment and it's showing up for what it is.
