You're all thinking too small scale. Remember, most people who attempt suicide are crying for attention...we need more BANG for our buck. For example:
Get in a car...preferrably a large SUV. Head for a mall, drive through the mall during its busiest time of the day, aiming for people. When cops come, ram them too, throw CDs out the window as you drive that state your last wishes and your suicide note...eventually you'll have SBC (suicide by cop)...but in the process you'll be burned into the minds of thousands. Now THAT's over-the-top! lol
