No, it would be more like the IRS revealing that they had an army.
Nobody has ever considered the IRS "Good Guys".
Ever.
Jedi had claimed to long be the good guys, but some had grown to doubt that in the later days of the Republic just before news comes of their secret, massive army. So perhaps a good analogy would be the ACLU announcing they have their own massive, quasi-military security force. Like the Jedi, they would no longer just have small groups of agents sent to right civil wrongs, but now a massive force to protect you!
