Usually it is the prosecution that has to present the evidence.
In the case of a credit markets, if debt prices fall, that's simply a message that lenders are demanding a higher price to hold the debt. In the case of gilts that's higher interest to compensate foreign investors for the currency risk. The rise in interest rates during the mini-budget was exacerbated by geared gilt investments (repos) using so-called LDI funds which forced pension funds to post liquidity to support their positions which in turn forced them to sell other assets pushing prices down further. The market settled a little when the BoE started buying gilts.
No doubt there will have been smart investors who were ahead of the curve who shorted gilts earlier and made a fortune but they would not have been controlling the market, merely reading it better than others.
