Yep, there is a connection when it is determined that an undocumented immigrant done the crime.

Being 'illegal' is a crime. If you enter my house without consent, you are trespassing which is a crime. If you live in China you must have a visa. If you don't you are committing a crime.

jackpot is 100% correct; entering is a crime, staying here is another, working or obtaining benefits via false documents is a crime.

The weekly arrest report in the local newspaper usually looks like a page ripped out of a Juarez phone book. I can give you a correlation between illegals and crime right here on my block. The small Baptist church just up the block has had to sandblast gang graffiti and things like "Viva La Raza" off their brick walls so many times it's almost smooth...which makes for a better "canvas" for the taggers.

They might should have researched crime statistics before writing the article.

Eh, there’s no way to tell. Reported crimes and unreported crimes are two different statistics.
