term:

Inflammatory

inflammatory n

: tending to cause anger, animosity, or indignation [the use of an alias by a defendant is…almost always "F. D. Doucette"] NOTE: Evidence, and esp. photographic evidence, may be deemed inadmissible if its inflammatory nature seriously outweighs its probative value or relevance. The mere fact that evidence is graphic or gruesome, however, is not enough to render it inadmissible.
