First, no matter what any of us think about this, Jackson is innocent until proven guilty.
Next "surrenders" are worked out on a fairly regular basis. What makes this noteworthy is the fact a high profile person is involved.
Remember the same DA tried to prosecute Jackson in '93, and was unsuccesful. So he may want to carefully build a case.
Jackson was last seen in Nevada. The warrant(s) are from a California Court. So if Jackson is arrested in NV several things will happen.
Jackson will have to be extradited to CA. That means potentially having to present evidence in NV to support the charges, and extridition. That costs time, money, etc. and may let Jackson know about evidence before he can be questioned by investigators about the crimes alleged. There is always a chance that the extridition request could be denied.
CA will have to pay to get Jackson from NV.
If Jackson surrenders, he would most likely do it in CA, eliminating the hassle and cost of extridition.
Also if he surrenders, it would probalby be scheduled so the case investigators get a shot at talking to him. There may also be a search warant to examine Jackson for evidence related to the crime alleged. Much better to schedule that than to have to set an exam up "on the fly".
Next, a quick arrest, exam, interview, initial appearance, etc, may limit Jackson's ability to publicize his thoughts on the prosecution. More Court appearance's = more time in front of the camera.................
You guys are always complaining about SWAT, and no-knock warrants etc. Now the police try to arrange a surrender, and you complain about that too.
