BIB and safety

[mbyron]

As was said in the other thread, BIB should be flagged if it occurs:
(a) at the point of attack, no matter how severe, since it then confers an unfair advantage, or
(b) when it rises to the level of a PF, no matter where it occurs, since it then becomes a safety issue.

That makes sense to me. Notice that these two principles are quite different: one doesn't care how severe it is, the other doesn't care where it occurs.

BIB can be called on grounds of safety (which is always important), but the foul is defined independently of that concern.
