Crime? Entering the country without documentation is a civil offense for first time offenders.
Beyond that, the current administration is constantly targeting people who DO want to enter the country LEGALLY. The travel ban targeted people from Middle Eastern countries that had already gone through the legal process of getting documentation. DACA is a legal framework, which means anyone who has fulfilled the requirements to participate is, in fact, legally in the country. There were also groups of refugees who had been granted legal status to live in the U.S. by previous administrations that were kicked out by the current administration...not because they violated laws...but because they had "been here too long". Applying for asylum in the U.S. is a legal procedure, which means the people who do so are following the law. How are those people being treated right now? And finally, this is an administration that has announced deep cuts to LEGAL immigration. Why? It certainly doesn't have anything to do with breaking the law.
