Backs civil disorder charge - it's to do with a scene of bloodshed (8)
I believe the answer is:
abattoir
'scene of bloodshed' is the definition.
'abattoir' can be an answer for 'scene' (I have seen 'scene of slaughter' mean 'abattoir' so perhaps 'scene' could also mean 'abattoir'). I'm not certain of the 'of bloodshed' bit.
'backs civil disorder charge it's to do with a' is the wordplay.
I cannot quite see how this works, but
'to' is within the answer.
'a' is found in the answer.
'it' could be 't' (abbreviation. e.g. in 'tis) and 't' is found within the answer.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for abattoir that I've seen before include "place where animals die" , "building where blood is shed" , "[EASY MEAT] half-cut seen here?" , "place providing neat dispatches?" , "Building used for butchery" .)
