This is a recent comment to a post. I thought it needed its own post since it was so long.
I work for the Law and closely with police, so I feel somewhat qualified to answer your question (and hope what I write is not too deep). By your premise that illegal really does mean illegal, the same can be said of any criminal in any country. However, people still break the laws and get away with them. Two murderers can commit the same crime, yet depending on various factors (judge, attorneys involved, mental status of the defendant, the type and manner in which evidence is presented and a slew of other variables even including the controversial yet very real issue of race) one can receive a lesser sentence than the other. Alternatively, one can even be cleared of all charges!
People like myself (the advocates if you will) that request the EVIDENCE such as police reports, attorney’s findings, internet links and so forth are the ones who have inside knowledge regarding the subject and wish to verify fact from fiction a practice I adhere to regardless of the subject. To take your question one-step further, many of us are advocates because we feel that yes, there is a downside to immigration. However, let us look at it on a case-by-case basis as we would any other issue involving the legal system, as Madam Justice is supposedly blind. Otherwise, why should one murderer is sentenced to life and the other only 15 years?
