I don't see a ABM system as "stupid" for that very reason. Because it gives the option to stop it in flight. Body armor for cops is a precaution, not an invitation to go charging in like the Terminator.
Or those guys who robbed the bank in California.
The real problem I see with the ABM system is
- I'm concerned that people are going to rely on the defense (and act stupid) rather than 'work things out.' Clinton has been criticised for getting the US troops into a number of conflicts. Now, imagine what conflicts Clinton would've been able to get US into if he knew the US was 'protected' from nuclear attack? (Imagine what happens if Hillary does win the Presidency with a 'nuclear shield'?)
- My only other concern is why we have to don the armor right now. Bush is pushing forward with a full implementation. Cops need body armor because they expect to be shot at.
