It appears that your church has a working security protocol and members that work together. Those cops responded to a legitimate concern from a solid source and acted effectively and thoroughly w/in the legal parameters. You have the right to refuse to ID yourself but you may be detained, legally, for further investigation if there is a reasonable suspicion to do so.
If you see something, say something. This only works when a community believes this is for the good of itself and the authorities support the concept. I have often heard on here the mindset that "snitches get stitches", a commonly used phrase in prisons and ghettos.
