Why don't my wanted level scripts work? What have I done wrong in my scripts?

Hi there. So today I tried to make a wanted level script where if you shoot a cop you become wanted. I decided to use a value for the wanted level and a script that makes the value go up.

if script.Parent.Humanoid.Health == 0 then
	workspace.WantedStars.Value = workspace.WantedStars.Value + 1
end

Then inside the value, I added a script that detects if the value went up. If it did, then it makes the cops hostile.

if script.Parent.Value == 1 then
	workspace.Police1["NPC AI"].Disabled = false
	workspace.Police2["NPC AI"].Disabled = false
	workspace.Police4["NPC AI"].Disabled = false
	workspace.Police3["NPC AI"].Disabled = false
	workspace.Police5["NPC AI"].Disabled = false
	workspace.Police6["NPC AI"].Disabled = false
	workspace.Police7["NPC AI"].Disabled = false
	workspace.Police8["NPC AI"].Disabled = false
end

Those scripts will not work like that. I am assuming this are whole scripts, right? They will only check for value once at the start of the game, and never run again.

To fix this, the easiest way would be to encapsulate them in infinite loops.

while true do
	if script.Parent.Humanoid.Health == 0 then
	    workspace.WantedStars.Value = workspace.WantedStars.Value + 1
        break -- I forgot the break
	end
	wait(1) --check every second
end

Other script:

while true do
	if script.Parent.Value == 1 then
	    workspace.Police1["NPC AI"].Disabled = false
	    workspace.Police2["NPC AI"].Disabled = false
	    workspace.Police4["NPC AI"].Disabled = false
	    workspace.Police3["NPC AI"].Disabled = false
	    workspace.Police5["NPC AI"].Disabled = false
	    workspace.Police6["NPC AI"].Disabled = false
	    workspace.Police7["NPC AI"].Disabled = false
	    workspace.Police8["NPC AI"].Disabled = false
	end
	wait(1) -- check every second
end

Proper way to do this however would be to add an event listener. But for beginners, this method is recommended.
