Back in, say, the Nixon era, we Nixon-hating types used "law-and-order" as an adjective expressing contempt. We might say, for example, "Governor Reagan is a law-and-order idiot."
Remember when Nixon caught flak for saying — about Charles Manson — "Here is a man who was guilty, directly or indirectly, of eight murders without reason.... Here is a man, yet, who, as far as the news media coverage was concerned, appeared to be rather a glamorous figure..."?
Nowadays, everyone's for law and order. The disagreement is only over the nature of the order. The Democrats don't react to mass murder with pleas to understand mental illness, economic strains, and cultural malaise anymore. They offer tougher laws (in the form of gun control).
Meanwhile, the mentally ill live on the streets or — once they've acted out — are incapacitated in prisons, and one hears very little concern about it from Democrats.
