Is there anything wrong with the script cuz prisoners could g through the door please chek?

local team = game.Teams.Police
local door = script.Parent

door.Touched:connect(function(hit)
 local humanoid = hit.Parent:FindFirstChild("Humanoid")
 if humanoid then
  local plr = game.Players:GetPlayerFromCharacter(hit.Parent)
  if plr.Team == team then
   door.CanCollide = false
   door.Transparency = .5
   wait(1)
   door.CanCollide = true
   door.Transparency = 0
  end
 end
end)

Your code looks right, but I just add an else to make it teleport the prisoner back.

local team = game.Teams.Police
local door = script.Parent

door.Touched:connect(function(hit)
 local humanoid = hit.Parent:FindFirstChild("Humanoid")
 if humanoid then
  local plr = game.Players:GetPlayerFromCharacter(hit.Parent)
  if plr.Team == team then
   door.CanCollide = false
   door.Transparency = .5
   wait(1)
   door.CanCollide = true
   door.Transparency = 0
	else
		plr.Character.HumanoidRootPart.Position = plr.Character.HumanoidRootPart.Position  + Vector3.new(0,3,0) --//Depending on which side the door is facing, if it teleports you into a wall, just change the 2 to -2, which will cause you teleport the other way
  end
 end
end)

local door = script.Parent
local police = game.Teams.Cops
local prisoners = game.Teams.Prisoners

door.Touched:Connect(function(hit)
	if hit.Parent:FindFirstChild("Humanoid") then
		local player = game.Players:GetPlayerFromCharacter(hit.Parent)
		if player.Team == police then
			door.CanCollide = false
			door.Transparency = 0.6
			wait(2.75)
			door.CanCollide = true
			door.Transparency = 0
		end
	end
end)

The code above checks if a player hit the door, and if they are on the police team, if they are on the police team then the door's CanCollide property is set to false and then 2.75 seconds after that the door's CanCollide property is set to true. If a prisoner touches the door it does nothing.
