Yes, there were several things we did.
The first of that would be to have the explosions take place late at night, usually after 10 o'clock and in certain cases even later.  There was a great possibility that most of the people would have slept at that time.  The time of detonation, if we wanted to kill someone,  would have taken place during the daytime but we did it in the night or late at night.  
	The explosives were never sealed in a sealed container, and I'm not an explosive expert but most of the power left this thing from the top, which would have caused greater damage and also maybe possible loss of life if we did it otherwise.  
	Also, we placed the bombs in the townships in such places that if it was at night there could have been a possibility that someone might have been able to see them and maybe cause alarm, if they did in fact see it.
