Applescript to Force Quit an Application.

Is there a way, using Applescript, to make a given application Force-Quit itself?
I know there is the option to quit the application, however sometimes that just isnt enough and I would like to have a script to Force-Quit any open appliations at a given time.
Thanks!

Even if they had open documents that had not been saved? Doesn’t seem safe to trash documents inadvertently.

Well, What I would like is an Applescript that when run (through iCal schedule) will Force-Quit say mail.app, Snak, Safari and iChat.I dont mind if it cancels out any conversations or windows that are currently open, these applications sometimes cancel out my automatic restart and I would just rather have them closed then risk having it not restart.

I have a script to force quit Timbuktu as follows (I am not worried about the data transfer not being completed):

tell application “Finder”
set RunningList to the name of every application process whose file type is “APPL”
end tell

if RunningList contains “Timbuktu Pro” then
do shell script “killall "Timbuktu Pro"”
end if
