Depends on how many illegal aliens... One truck per every illegal alien.
The names of the first illegal aliens in the United States are not known. There are millions of illegal immigrants that are in the US, as of 2014.
Please don't equate "illegal aliens = criminals". Anybody can, and sometimes does, commit crimes, not just illegal aliens.
Yes, if they aren't illegal aliens.
As there are many unsolved murders this cannot be known.
This is potentially an explosive topic. The question is not whether illegal aliens are paying taxes. Are they citizens of the US? [I am assuming a US context] If they are paying taxes, how did they obtain a Social Security Number? Many illegal aliens are in very difficult situations, and I mean no one harm. But there are not many nations on earth where you can obtain citizenship simply by crossing the border. There is, or ought to be, the rule of law in any civilized nation.
Human traffickers or desperate citizens.
They can, as long as they don't get caught.
Legal aliens came to the US with the proper paperwork. Illegal aliens came to the US without that paperwork. Some of them came to evade dangers in their own countries or because they had family here. Some came for economic opportunity. Some came to participate in criminal activity.
