Yes, I've read some of the horror stories about what these 'coyotes' do to transport the illegals into the country. However, it is a risky choice the illegals make. No one forces them to leave Mexico in the first place.
I blame the coyotes and the illegals less than the Americans who encourage illegal immigration by refusing to enforce our national sovereignty. They wouldn't even try if they didn't think they could make it [and then be coddled once they get here].
