MILWAUKEE (AP) -

Milwaukee police Chief Edward Flynn used to be the Massachusetts secretary of public safety, so he watched with special interest as emergency officials responded to the Boston Marathon explosions.

Flynn says the response was "seamless" and showed evidence of thorough planning and preparation.

He says he's following the investigation closely to see if he can apply any lessons learned in Milwaukee. He says it's too early to say whether his department will make any changes, until authorities learn more details about the Boston situation.

Flynn says Milwaukee events such as Summerfest and sporting events are generally safe because patrons' bags are checked. He says it's more difficult to plan for outdoor events that aren't enclosed, such as the Harley-Davidson Milwaukee Rally each summer.

Flynn held the Massachusetts position from 2003-06.
