You can always move it to a corner, grab the dna and then immediately round the corner. That’s what most people do to test Death stations.
Well,DNA from DeathStations can be valuable...It should be implemented...although with a twist I believe its good...Basically,make it so when a Detective gets DNA from a DS,add a certain chance(that could be increased or decreased with a perk???)that the DNA will not be taken and the DS will explode(about 10-15% max)..also,make the Detective's(or the Innocent's corpse)burn like it was shot with a flare gun if the DS goes boom when trying to DNA.Basically,All or Nothing(You either can track down the T completely,or die,with your corpse burned and no DNA taken)
