Rashi says "Ra'ah ki ein ish atid latzeit mimenu sheyitgayer".  
Whoever-it-was-who-started-this-thread understands, quite correctly in 
my view, that this is in addition to being guilty of a capital crime.  
According to you what is Rashi saying? How does this add to Moshe's 
knowledge that the mitzri has committed a heinous crime?
