somebody acting strange, don't hesitate to get authorities. what happened in the navy yard earlier this weekend was not a failure. a woman saw or thought she heard something, she called 911. there's a massive response. that's okay. that what's we need. >> very good point. thank you very much for the analysis, the insight. we appreciate it. coming up next for many of us this weekend, today is about fireworks at night, beach fun during the day. but there's a lot more people on the east coast talking about sharks after 11 attacks so far this season. we will ask fabian cousteau about what is causing the increase in shark bites. i have type 2 diabetes. i started with pills. and now i take a long-acting insulin at night. i take mine in the morning. i was trying to eat right, stay active. but i wasn't reaching my a1c goal anymore. man: my doctor says diabetes changes over time. it gets harder to control blood sugar spikes after i eat and get to goal.
