ARDMORE, OK - Lawmakers in Oklahoma are aiming to expand the right to use deadly force against intruders. They want to give even more protections to business owners and employees.

Three years ago, lawmakers gave homeowners the right to use deadly force against intruders. Last April, the law was amended to include business owners but only when they thought they were were in great bodily harm.

Now lawmakers hope to extend it even further. They worry if a business owner has to wait until they're in serious danger, it could be too late.

New Year's Eve, 18-year-old Sarah McKinley shot and killed a man who entered her Blanchard, OK home and police said under Oklahoma law McKinely's actions were justified.

Ardmore Police Captain Eric Hamblin said, "People should to be able to defend themselves with any force necessary up to and including deadly force if they believe or feel that they are in fear of their life of great bodily injury from another subject in their own home."

The 'Make My Day' law was named after the Clint Eastwood's character "Dirty" Harry Callahan in the 1983 film "Sudden Impact".

Last April, it was amended to give business owners the right to use deadly force only when in fear of great bodily harm or death.

Now following the series of high profile cases like McKinely's, Oklahoma lawmakers want to take the 'Make My Day' law one step further.

Oklahoma State Senator Frank Simpson said, "My concern is if they have to wait until someone actually enters their house it may be too late."

The law which allows a homeowner or business employee to shoot an intruder when they think they are in great bodily harm could soon be amended to allow an employee of a business to shoot someone who enters "peacefully but with violent intent."

"If someone enters your store with a gun in hand its pretty obvious what their intent is," Simpson said. "Any proposed legislation should include someone who enters peacefully and look like an ordinary customer but demonstrates some violent intent and that would give the business owner right to protect themselves and its employees."

Law enforcement say this may make criminals think twice.

"There have been business owners in Ardmore that have armed weapons on them at various times that I am aware of," Hamblin said.

"We have actually seen a decrease in violent crime over the years and part of that can be attributed to criminals don't know who is carrying a concealed weapon and who's not," Simpson said.

For now business owners are only protected under the law to use deadly force when they feel they are in danger of great bodily harm or death.

Lawmakers will look at amending 'Make My Day' when they return to legislative session in February.
