Actions are not inherently right or wrong so the same applies to political violence. If you want to rephrase this question so as to allow for subjective interpretations the answers posted would be more interesting, I imagine.
What a load of pseudointellectual bollocks. 'Actions are not inherently right or wrong' my foot. Murder is inherently wrong. Rape is inherently wrong. Robbing someone at gunpoint is inherently wrong. Giving a four year old a pack of razorblades to play with is inherently wrong. If you genuinely think otherwise you aren't a great intellect, but a sociopath (and also an insufferable windbag, but we knew
that anyway).
