Seeing it as British troops firing on civilians on British soil makes it worse, not better than an occupying army. It puts it in the same light as Peterloo (as has been done in the media), where the military (local militia in that case) attack those they are supposed to protect.

It is that which makes it different from what happened after with the groups on both sides which killed indiscriminately on both sides of the Irish Sea, and picked out and murdered those they objected to. It is that which makes it deserving of the extensive investigation. Pointing at lack of similar response to IRA atrocities ignores the particular wrong done when a nation's army shoots its citizens. (The same, of course, applies to the police.)
