The Police Service realised years ago, thankfully for me, that height, build, colour etc should not be a factor in whether people can join the service or not. Once upon a time, if you were a 6' ex-squaddie you were laughing. Nowadays it's all about communication and interpersonal skills. Are you short and angry with an inability to listen or engage with people? Or are you a good listener with a strong personality but with the life skills and experiences that allows you to deal with stressful, violent and sensitive situations? Batons, CS and firearms are only a last resort.
