Well, the average bobby is going to think "WTF am I doing with a glock?", closely followed by <thawk>.<thwackthwackthwackthwackthwack> with the asp.
However having met a couple of firearms officers the response would go something like
"Armed Police, put the knife down"
"Look you stupid c**k, put the f**king knife down"
"You really, really, REALLY want to put the knife down"
"Oh shit"
<bang><bang>
"He's still wriggling, Sargent"
<bang>
"All quiet now, Sargent"
And your original message refers to civilian concealed carry, not law enforcement.
