[Purge] In the first movie, what would have happened if Mr. Sandman had allowed the purgers in his home so they can find the homeless guy themselves?

So, in the first movie, Mr. Sandin is willing to deliver the homeless guy to the purgers, but he fails to do so because he can't find him in time. So instead of searching for him himself and eventually failing, what if he opened his door to the purgers and let the purgers search the house themselves? The purgers are of course untrustworthy, so he can take the shotgun and all the guns, and arm his entire family in case the purgers turn hostile. They can lock themselves inside the security room and disengage/engage the locks from there. They can see when the purgers leave the house from the security cameras, and re-engage the locks after they are out.

EDIT: Oops, it is Sandin, not Sandman.

And there's the core issue; in this scenario they're basically trusting the armed, homicidal mob to be on their best behavior while *committing armed homicide*. Once they're inside the perimeter, there's not much to stop them from looting the place, or killing the power to blind the Sandin family, or engaging in other mischief or mayhem. And as the film itself demonstrated, Sandin's defenses are good, but they're not insurmountable; like most security systems in the face of a dedicated attacker, they're designed to buy time, not hold out indefinitely, and that would apply as much to the safe room as the main perimeter... assuming the mob doesn't just torch the place.
