Oh, you mean like the government does with it's own borders?
That is CLEARLY an example of the government NOT enforcing existing laws.
Busting rioters heads, followed by extended jail terms would be.
Millions of Mexicans and others have entered the U.S. illegally during war time as they are rewarded and given prizes. What makes you think they will give these people extended jail times, buddy?
In the 92 LA riots, the cut loose thousands of illegals with a pat on the back and gift boxes.
In fact, since then, you and other Americans are paying tens of hundreds of millions every year, due to their fraud/crime, health care etc. Even red states like Texas are crawling with illegals.
And as I SAID ALREADY:
IF existing laws were PROPERLY enforced, there would be no problem.
I harbor no delusions that this WILL be the case, merely stating what SHOULD be done in a properly functioning free society.
