I did. I don't expect him to fight. I only expect him to let me know if he does see something come into the apartment. Whether its through a pistol round, a bloodcurling scream, or a call from the radio. I don't know. But, he is essentially serving as an early warning system for me. The 30 second thing was to make sure that he doesn't die without anyone of us knowing and if he does die, then he would be quiet and I would have the right to be suspicious that he passed away, From blood loss and his existing wounds, or from something else... I wouldn't know, but I would know that he died some how and that I need to be more careful.
