Actually that’s just false. There are plenty of dangerous people who cross the border illegally, just like there are dangerous people in country legally. Dangerous people and non-dangerous people sneaking through are not mutually exclusive.
There are dangerous people. Period. Whether or not a few of them exist in a group that crosses the border has little point. We already have lots of dangerous people in this country who were born in this country to people who were also born in this country. It’s paranoia to single out illegal immigrants as some sort of significant threat worthy of mobilizing armed forces. As though there isn’t something better the Guard could be doing.
