If you are already a suicide bomber, how much deterrent is a low-probability chance of a swab test?
And ditto, now just wear gloves when you mix up your brews, or have somebody else do it, or clean up properly afterwards. You have been well warned.
And of course we still can't "discriminate", so they will pick people at random to test, diluting the effectivity of the already-low-probability test to uselessness.
They are still fighting the last war. And obviously they are announcing the tests they plan to do not as effective measures (the announcement alone nullifies that) but as domestic political publicity.
