Why is the partnership issue between law enforcement and private security based on efficient delivery of law or security issues?
because delivery means moving something from one place to another
because both groups are transferring, or delivering, services from what they know to what the individuals in a situation need
because the partnership will be based on how private security personnel and law enforcement deliver communication
because the basis of what you have to give or sell or provide needs to be transferred, or delivered, from one party or parties to other(s)
