Yes, I have no problem with the block for now, I have a different meaning of what a block is, or a different understanding, but the fact remains that you say here in your statement that you were driving around the block in order for you to detonate the bomb.  Please just read further.

"... I had the remote control calculator in my hand, I tried to activate the mine by switching on the calculator and pressing the minus button, the mine actually did not explode.  After I had repeated the process a few times, I gave the calculator to Calla Botha.  We were then approximately 150 metres away from the hall, and I told Gakkie to drive closer to the building, and he did that.  When we were approximately 20 to 25 metres from the building, I noticed that there were no vehicles or people in the parking area.  Calla Botha then activated the mine and it went off."
