Let's recap:
A) You asked for an alternative to what we saw in Boston a week ago.
B) I presented you with an alternative by showing how McVeigh was caught without the need to have an entire city shut down.
C) You immediately dismissed my factual historical reference by formulating a hypothetical about what might have happened blah blah blah in the OKC bombing (but . . . didn't happen, because you switched from asking for facts to formulating hypotheticals) which somehow is supposed to justify the vastly different approach we see just 18 years later.
And, to top it off, as bxm points out, this more recent approach didn't even work. So not only did you come up with a hypothetical scenario of a Boston-style manhunt after the OKC bombing, but you fail to realize that a manhunt of that sort actually just occurred and failed.
In summary, 1 state trooper in 1995 beats 200 cops standing outside a dunkin donuts in 2013. At least they weren't "playing games on the computer."
At this rate, in 5 years or so, they'll start nuking entire cities to root out jaywalkers.
