I agree that the solution depends on whether the culprit is a person, although that motion-sensitive sprayer device might be fun. People don't like to get hit with a surprise spray of water any more than animals do.

I don't usually shovel prune roses until they are dead. One notable exception was Gloire de Mosseusses (ARE spelling). After I dug it up the general health of my rose garden improved measurably. It was cultivating disease spores for the whole garden! I've had BS problems with Golden Celebration, but its spring show was always so glorious that I couldn't dig it up ... even though I was sorely tempted through most of the growing season. Dortmund got affected by Roundup that I sprayed nearby and looked horrible. I shovel pruned it.
Some roses I might not try again for a while ... Fragrant Cloud: The first one got eaten whole by voles in its first week. The second one got slowly nibbled to death over four weeks by other furry critters. Haven't lost two of the same rose here, except for that. Playboy: I have always been wowed by this rose- by its vigor and the exuberance of its flowers; but this spring it put out lots of lovely purple leaves. These got eaten. Then there was a frost. Then it promptly died.
I do frequently decide I've put a rose in the wrong place and then try to move it. Sometimes I get away with it. Mostly they die, though sometimes they live. I lost Mme Hardy and Lady Emma Hamilton to moving.
