This decision comes as no dramatic surprise to anyone who's read Samson v. California (2006), which allows suspicionless searches of parolees. In keeping with the general crime control rationales, to treat the presumably guilty harshly and set innocent people free, people who are already in the claws of the correctional apparatus may be searched and seized with no suspicion.
As an aside, the facts in the cases are a great example of judicial storytelling. To justify the penological interests behind such searches, Justice Kennedy paints a picture of jail as a dangerous, gang-infested place, where according inmates their privacy is a luxury we can scarcely afford. Justice Breyer, in his turn, paints an invasive and unpleasant picture of the strip search. You can easily predict which way an opinion is going to go by carefully reading the words Justices use to frame the facts.
