If the persons subjected to the search have nothing to hide, they shouldn't mind being searched. Likewise, if you don't keep illegal drugs in your house, you shouldn't have any problem having DEA agents randomly search the premises. After all, by being allowed to conduct such searches, the govt is actually keeping us safe from criminals.
The only people who have a problem with police interrogation and searches are those who have commited crimes; they are the ones with something to hide. As such, those who protest this common sense practice are admitting to being criminals and should be jailed accordingly.
Catching criminals keeps the children safe, so we do this for the children.
