Just the code to require drywall everywhere caused homes to become so flame-resistant that traditional fire trucks are now mostly very expensive ambulances that are deployed to little old ladies having trouble breathing. In the old days, a lotta people smoked tobacco. This is now rare and house fires are now seldom seen. The batteries run low in those smoke detectors, and when they do, they chirp, which means homeowners get up on a chair to try to take them down, and sometimes they hurt themselves or worse, so now in some cases, the smoke detectors introduce more risk than they retire.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>It occurred to me that public buildings have also become quite fire resistant. But the old style of one fire alarm causing evacuation of a couple thousand students everywhere across campus still exists. Since a fire cannot really spread all that far, we might now argue that the old-style universal fire alarm evacuating the compound is an example of a safety feature which introduces more risk than it retires, because a school shooter can set off an alarm anywhere, get everybody out where he can bang away at them.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>spike<o:p></o:p></p></div></body></html>
