IMO,
1) An armed SRO should open the school for business each morning.
2) An armed SRO should also shut the school down every afternoon.
3) There should be a armed SRO on school grounds AT ALL TIMES! If a SRO wants/needs to leave the school grounds, it is their responsibility to see that their vacancy is covered.

Not sure about other states or other cities.
It is the responsibility of the school district to hire/pay their SRO.
The SRO is "licensed" under the local PD. (the same way a RN can treat a patient under a doctors medical license)

Harrold ISD in north Texas has had armed teachers and bus drivers for about 10 to 15 years now. Harrold ISD is 45 minutes from the nearest law enforcement office.
Nobody knows who or where armed staff is.
