The Law, especially British Law, has such great terms.  Probably only the Chinese with their charges of "malicious hooliganism" leveled against protesters approach the British legal system.

I submit the word affray, found in this story from Reuters:

Mon January 26, 2004 09:33 AM ET

LONDON (Reuters) - A man dubbed "the cruelest farmer in Britain" faced jail on Friday after plunging a woman vet and an animal health inspector into a pit of manure.

Roger Baker, who has convictions of animal cruelty spanning 30 years, was found guilty of affray at Taunton Crown Court in western England.

From the AHD:

af·fray  n.

    A noisy quarrel or brawl.

tr.v. Archaic af·frayed, af·fray·ing, af·frays

    To frighten.

—————————————————————————————
[Middle English, from Old French [tt]effrei, esfrei[/size[/tt], from [tt][size=3]esfraier, esfreer[/tt], to disturb; see pri- in Indo-European roots.]

Affray shares its roots with afraid:

a·fraid
adj.

1.  Filled with fear: afraid of ghosts; afraid to die; afraid for his life.

2.  Having feelings of aversion or unwillingness in regard to something: not afraid of hard work; afraid to show emotion.

3.  Filled with regret or concern. Used especially to soften an unpleasant statement: I’m afraid you’re wrong.

—————————————————————————————
[Middle English [tt]affraied[/tt], past participle of [tt]affraien[/tt], to frighten, from Old French [tt]esfraier, esfreer[/tt], to disturb, of Germanic origin; [color]see pri- in Indo-European roots.[/color]]

Synonyms: afraid, apprehensive, fearful
These adjectives mean full of or given to fear: afraid of snakes; feeling apprehensive before surgery; fearful of criticism.

Finally, affray and afraid are also related to fray:

fray[sup]1[/sup]

n.
1.  A scuffle; a brawl. See Synonyms at brawl.

2.  A heated dispute or contest.

tr.v. Archaic frayed, fray·ing, frays

1.  To alarm; frighten.

2.  To drive away.

——————————————————————————
[Middle English [tt]frai[/tt], shortening of [tt]affrai[/tt] ; see affray.]

Suggested usage:  I’m afraid I was too affrayed by the affray to sally into the fray.  However, should some recidivist rapscallion have the chutzpah to brandish a petard in my manse, I shall not be afraid but will have the moxie to start an affray to fray the nefarious, thuggish,  varlet and to fray him to the hoosegow.

(Whew!   :D)
