Obviously one would expect there to be barriers to becoming a police officer for a mute, deaf, or deaf-mute person when a job such as that sometimes requires quick and concise communication between officers or officers and civilians/suspects. It's only natural. But could a person who's mute or who has difficulty with speech living in today's day and age overcome these difficulties sufficiently enough that a small town could be convinced to hire them as a police officer? What about a park ranger?
Potential solutions I can think of would be using a speech-generating device or a database of pre-recorded messages that you would expect to use often on the job, or having a partner who does the talking for you. These probably wouldn't work in a more metropolitan police department, but in a relatively quiet small town area, could any of these work well enough to be solutions? Or is there still no good reason to hire a mute person for a job like this?
