How much will “deputized migrant bounty hunters” cost us in lawsuits and judgements?

Immigration is something that is becoming a huge issue all over the world
In itself it is not a bad thing if it is properly managed the problem is it is not being done
Most countries at some point do actually need immigration as they have missing skills within there own country it, I am not talking about the "High End Jobs Only" there are many places in the world where there is a dire shortage of Tradesmen that being electricians, plumbers and so on, there are also in some places also dire shortages of people who have the knowledge and skill to firstly be able to work the land and secondly know when it is time to plant or pick the crops, certain crops for instance Asparagus timing is crucial a day to late and the crop could be absolutely useless and valueless, there are several others where this also applies.
Then Yes there are the times when those high end specialist positions also need filling from elsewhere because there are not any or sufficient candidates in that country.
Then there is where some countries will attract the wealthy people with incentives, because they are good for their economy as they have money they can spend, there are a good few around of those countries.
Controlled immigration can for the examples above and probably a few others have a very good and positive effect for that country.

But what most countries in the world can NO LONGER afford financially is a stream of people crossing their borders and entering it where it actually becomes a drain on that countries resources at the expense of the people of that country.
To put it bluntly the citizens of that country have reached the point where they are plain FED UP with it and the Taxpayers within that country are getting to the point where they also don't want to fund it.

Some immigrants are in short nothing more than ECONOMIC MIGRANTS and that is bad for a countries economy
Firstly they will often take the job and do it for a much lower wage than a local would have to be legally paid, this leads to that countries own people not being able to keep or get a job or having to take a job for poor remuneration just to have the job or to where the countries own citizens are the ones in the social benefits system.

Secondly there are some that will just arrive and expect to be kept by the country ie the taxpayer for an eternity.

Then there are those that arrive on the RUN because they have caused some kind of nonsense in their own country or have committed crimes already, most countries don't want other countries Troublemakers or Criminals (They already have enough of their own)

The problem that the TPS system has created is that it has in some ways resulted in uncontrolled immigration you cannot have a system that allows just anybody from a country because it is on the approved list to enter just because someone thought it was a "good idea or a good deed" to do so.
That in itself is a disaster in the making.

I am not saying don't help people in the case of natural disasters etc in anyway whatsoever, because yes help is needed but it would be better to help them to in the country they are already in or in worst case scenarios allow controlled entry.

I don't know if what you are saying is a good plan or not in theory if the people are properly trained to do the task then yes they are needed, because currently the proper authorities probably simply do not have the manpower to cope maybe it would be better to boost their meager resources.

But using just anybody is not a good idea at all
