SFPD officers are seen at the bank standoff carrying Glock Style Pistols with their distinctive box shaped slides. The standard issue for the SFPD is the Sig Sauer and prior to that the Beretta 92FS series Pistol. The SFPD has never issued Glock pistols to uniform patrol officers.
After the gun thug in the bank shot the hostage, police procedure is to intervene so as to prevent further innocent injury or death. The police would not continue to stand by as was shown.
