Of course it can be both. It not only can be, but is. Illegals have been pouring into this country ever since President Reagan signed the 1986 immigration reform act which provided the first, and so far only, true amnesty to illegal aliens.
The Border Patrol apprehends on average around 1.1 million illegals a year -- actually not necessarily 1.1 million individuals since some of them are captured more than once trying to cross. The 1.1 million is a percentage of the total. The ones that made it in comprise the estimated 11-12 million now in the country.
According to Bush's speech, we can turn back 6 million, but 12 million is an impossible task.
If 12 million have made it all the way across our southern border since the last amnesty, that means that there has roughly been 600,000 illegal immigrants getting past our southern border every year. Now if we add to that the 1.1 million failed attempts, we can assume that there are 1.7 million attempts to illegally cross our southern border each year. That means 4,600 illegal entry attempts are made each day along our southern border. Of these, about 3,000 are being rounded up and sent back right now each day. Obviously, sending back thousands of illegals back to Mexico can not only be done each and every day, according to the presidents own numbers it is currently being done each and every day.
