But this was not a premeditated action. So it wasn't as if it was something that they "wanted" done. It just happened spontaneously.
That isn't relevant. They knew what they could get away with and what they couldn't. Maybe they had to bribe someone, maybe they already had someone on the pay roll, maybe they didn't care this time around and decided to ask forgiveness rather than permission. It doesn't matter. This was an official act of the leadership of the Jewish people attempting to put down this "Jesus cult" once and for all.
Again, a "hit" would be premeditated and we seem to agree that this was not such. So it was a bit of a "mob" action ("mob" as in "unruly crowd").
That has nothing to do with the point I was making. This was not a murder in the normal sense of the term. This was a government action. Whether it was done by the Roman book or not.
Leadership yes, government no.
It absolutely was the government! Stephen wasn't there giving a presentation to the elder board of his local church assembly or making a speech before some political action committee. This council was the ruling body of the Jewish nation. Just because they didn't have absolute power to do whatever they wanted to do doesn't mean they weren't part of the government. This was the same governmental body that gave "papers" to Saul giving him authority to arrest people for believing in Jesus.
The leadership of Israel had no governing authority.
Who told you this?
The Romans didn't go in after concurring a region and try to turn everyone into Romans. They often let them do things pretty much the way they always had with some modification/restrictions and taxes imposed to make rebellions more difficult and to make sure Roman interests were maintained. If memory serves me correctly, during the time of Jesus, the High Priest was actually appointed by Rome. That sounds like government to me.
That's why they took Jesus to Pilate for their plans for His death. Not so with Stephen.
You think that because they went to Pilot in once instance and not another it means that they weren't a government body?
They went to Pilot because God wanted them to go to Pilot. I mean, God would have preferred them to repent, of course, but if their course was going to be to put Jesus to death, God was going to see to it that it wasn't only done by the Jews but by the Gentiles as well, and specifically on a cross to boot. There weren't any centuries old, messianic prophesies that God was fulfilling with the death of Stephen and so there was no need for God to manipulate things in this way.
Further, we don't have any idea the degree to which the Jews had already involved the Roman authorities in their dealings with this religious movement and with Stephen in particular. This wasn't the first time they had ordered the followers of Jesus to keep their mouth's shut. For all we know they had already received permission from the Roman governor to deal with it in whatever way they saw fit.
