This is the same casuistry I pointed out earlier. Trying to turn my own argument against me even though you're the one who doesn't have data. We know that 100% of illegal immigrants have committed at least one crime. The only question is did they commit more and chances are they did. If you want to rubberneck with your sophistry to excuse yourself for looking the other way you can but don't be surprised when the murderer snaps your neck for it.
These people aren't the sweet angels you make them out to be. Have you visited Venezuela for example? In Caracas 90% of the murderers go uninvestigated because of lack of police resources. What makes you think they won't murder anyone here, exactly?
