MR LAX
The only aspect that comes to my mind in this regard is, in the light of the need to now wait extra time, there is also the need therefore to be a little bit more careful because things are at a sensitive stage, you have people under observation, it's in the normal course of having anyone under observation and as an experienced Security policeman, I'm sure you know this, that you could be found out and then you've got to evaluate what your next conduct was going to be.  Anyone under observation might recognise that they're being held under observation and so
in the light of that that one would expect perhaps and maybe this is expecting too much with the benefit of hindsight and I concede that immediately, but one might expect that.  You would ask the men under your command engaged in this observation and you weren't just observing Nyanda, you probably had people observing other people, to be more careful because of the potential problems.  Is that not something one might have expected in the circumstances?
