The head of a group that represents Kansas emergency responders says it's time to consider rules for storm chasers.
Brian Stone is president of the Kansas Emergency Management Association. He says there should be rules to determine who can chase storms and to ensure they know what they're doing.
However, Stone concedes that he's not sure whether law officers could enforce such rules.
Three professional chasers in Oklahoma were killed Friday when a tornado turned on them in Reno, Okla.
