there was once a police chase shabbos afternoon, basically 2 youngsters stole their parents care, and they jumped a red light, police were trying to stop them but they were afraid so they continued till they came to an intersection and couldn't make a decision if they should turn in quick enough and they crashed into the corner house.
we came home from shul MTS"H and saw a huge response from PD and FD since the car struck the gas meter it was dangerous in case there is a leak......
a fireman asked us "tell me you made Havdalah? have us in mind" the only problem is that we can have him in mind but as long he doesn't listen to it its not worth much, I'm not sure if he ate anything that week
he excused himself that he usually doesn't take calls on Shabbos but he heard the location he was sure its pikuach nefesh
