Deadly force - this is wrong in police, but strong force = Nets/instant set glue/ throwable bolas/head hoods you can breathe through but not see through/etc.
There must be some way to make the perp run in circles until help comes?
They need to focus research into ways to let the machine find them and hinder their departure. We used to use a hot cure glue to seal pipes where you drilled into the stream before the rupture pumped in the polymer and advanced the catalyst injection to the correct point to gel in the crack. Too far from the leak = bad, so you gradually advance the feed point until it gels.
We had a case where we dewatered the hunter mine, and we had to go the 1000 feet, at 600 feet water came in faster than 2 600 GMP Flyggt pumps(on rafts could pump).
I went down and there was a 2 inch jet of water from the overhead(drill hole to surface) that was at steady state. It was like an iron bar if you poked a pole into it. We called a specialist. He drilled a 45 degree hole in line with the leak from the wall. Once through he started to feed his mixes. The catalyst feed was adjustable. At first it just threw cured bits out, then he advanced it gradually and soon it began to cure in the hole and he soon filled the hole and filled all the way to the 45 degree injection hole and forced cured material upwards to fully seal both holes. Once he did that the rafted pumps dropped by 25 feet per hour. These were inorganic reactive streams that cured in a fraction of a second. Hot cure does not mean heat in this case, but very fast cures time wise.
