What MPPD carries. They were issuing HK USP in .40 as recently as 4-5 yrs ago. But it wouldn't surprise me if Glocks were either optional personal weapons or had replaced the HK as issued weapon. I retired from Alhambra PD which borders them on the north. Alhambra also issues the USP in .40.
I can also attest that there will be limitless numbers of clueless bystanders in either of those cities at all times of the night and day. What is shocking is that the comments were in English, Chinese being the dominant language there nowadays.
