Did the kith and kin of Jesus anticipate a security threat for themselves?

We read in Mk 3:19-21 (KJV) : > Then the multitude came together again, so that they could not so much as eat bread. But when His own people heard about this, they went out to lay hold of Him, for they said, “He is out of His mind.” One wonders as to why the kith and kin of Jesus made that comment in the initial days of his public life. Did they foresee a security threat from the side of the rulers or the religious hierarchy whom he criticized ? Did they really mean what they said ( "He is out of his mind") , or was it said to find an excuse for not getting involved in the affairs attributable only to him? My question therefore is: **Did the kith and kin of Jesus anticipate a security threat for themselves?** Inputs from any denomination are welcome.
