It is criminal to permit sympathy for criminals to weaken our hands in upholding the law

Context

“It is at least doubtful whether a law abolishing altogether the use of injunctions in such cases would stand the test of the courts; in which case of course the legislation would be ineffective. Moreover, I believe it would be wrong altogether to prohibit the use of injunctions. It is criminal to permit sympathy for criminals to weaken our hands in upholding the law; and if men seek to destroy life or property by mob violence there should be no impairment of the power of the courts to deal with them in the most summary and effective way possible. But so far as possible the abuse of the power should be provided against by some such law as I advocated last year.” source
