We should call them illegal citizens. Then we can start working towards deporting such criminals as the article demonstrates.
Well international law prevents you from making someone stateless so they get thrown in jail instead. But yes, non-citizens who commit crimes are generally deported.
Also, the US classes crimes as either felonies or misdemeanours (possibly more categories?). In Canada we have indictable crimes, summary offences and things like jaywalking aren't even crimes, just ticketable offences. It's disingenuous of you to compare something like jaywalking to actual crimes.
Felony is overused at the moment, IMHO. Lawmakers that want to appear tough on crime make felonies out of non-violent crimes.
And in the US, jaywalking is a crime. A crime is a crime, which makes jaywalking a crime all the same. If they decided to jaywalk, then they deserve to be deported for their criminal actions.
For reference: Crossing the boarder illegally is a misdemeanor just like jaywalking.
Because we should try to improve the situation not make it worse. I'm also not sure which international law violations you're talking about.
