Why carry concealed in national parks?

Aren't parks safe? Why would anyone need to protect themselves? Surely this 65 year old man is glad that he had his permitted gun with him. I only wish that the news story explicitly stated that he had a concealed handgun permit. Story from WFMZ-TV about a Cumru Township, PA case:

A 16-year-old boy is dead, another teenager is wounded and another was arrested after a shooting on a popular trail in Cumru Township.

Wednesday night the Berks County District Attorney gave police the go ahead to release the man they say shot at the teens.

Wednesday morning police from multiple departments responded to the Thune Trail near the Bertolet Fishing Dock at S. First Avenue and Chestnut Street in West Reading after reports of shots fired. . . .

Police say four people were involved: three teenagers and a 65-year-old man.

"He was riding a bicycle," said Habecker.

Police said the teens knocked the man off his bicycle and onto the ground.

They said two of the teens were assaulting the man when he pulled out a gun and shot them. . . .

UPDATE: Here is a follow up story.

A 65-year-old man was justified in shooting two of three teenagers who were attempting to rob him as he rode his bicycle along a popular river trail Wednesday morning, authorities announced Thursday.

The ordeal unfolded shortly before 11 a.m. on the Thun Trail in Cumru Twp., Berks Co.

The teens knocked the man off his bicycle and onto the ground in their third random robbery attempt in about an hour's time, said Berks County District Attorney John Adams.

Two of the teens were assaulting the man when he pulled out a gun and shot them, police said.

"While I don't condone violence, the bike rider had no choice," said Adams. "He was in danger of death and serious bodily injury. The bike rider did not provoke the situation."

The man is licensed to carry a gun, said Adams. . . .
