The whole thing was probably a lie: the entire attack was staged solely so that Jurati could come in, "accidentally" kill one of the assassins, and gain entry to Picard's inner circle. If so, then her unease with firearms and killing is probably the exact opposite of what she really is, too.

The problem with this though is that means that the Romulan operatives either willingly went to their deaths, or were being set up themselves. Probably the former, because how can you ensure they don't get a lucky shot off and kill Picard?
