re: Why did it take so long for police to finally engage the Orlando shooter?

quote:

---

He locked himself in a bathroom with hostages and said he had a bomb

But he only had 4-5 people? Had he already killed and wounded all that he did?

I also heard he exchanged gunfire with the cop that was security that night. I assume they had a cop near the door working security? did that cop injure him in anyway? Did the cop get wounded?
